+
+    OpenGL Extension #538
+    OpenGL ES Extension #319
+
+Dependencies
+
+    OpenGL 4.0 or OpenGL ES 3.2 are required.
+
+    This extension is written against the OpenGL 4.6 specification
+    (Core Profile) (February 2, 2019) and OpenGL ES 3.2 specification
+    (February 2, 2019).
+
+    This extension is written against the OpenGL ES Shading Language 3.20.05
+    specification and OpenGL Shading Language 4.60.6 specification.
+    
+    This extension interacts with OVR_multiview2.
+    
+    OVR_multiview is required.
+
+Overview
+
+    OVR_multiview introduced multiview rendering to OpenGL and OpenGL ES.
+    
+    This extension removes one of the limitations of the OVR_multiview 
+    extension by allowing the use of tessellation control, tessellation 
+    evaluation, and geometry shaders during multiview rendering. 
+    OVR_multiview by itself forbids the use of any of these shader types.
+    
+    When using tessellation control, tessellation evaluation, and geometry 
+    shaders during multiview rendering, any such shader must use the 
+    "num_views" layout qualifier provided by the matching shading language 
+    extension to specify a view count. The view count specified in these 
+    shaders must match the count specified in the vertex shader. Additionally, 
+    the shading language extension allows these shaders to use the 
+    gl_ViewID_OVR built-in to handle tessellation or geometry shader processing 
+    differently for each view.
+    
+    OVR_multiview2 extends OVR_multiview by allowing view-dependent values
+    for any vertex attributes instead of just the position. This new extension
+    does not imply the availability of OVR_multiview2, but if both are available,
+    view-dependent values for any vertex attributes are also allowed in 
+    tessellation control, tessellation evaluation, and geometry shaders.
+    
+    
+New Tokens
+
+    None.
+
+    
+New Procedures and Functions
+
+    None.
+    
+    
+Modifications to Chapter 9 of the OpenGL ES 3.2 Specification as well as
+Chapter 9 of the OpenGL 4.6 Specification (Framebuffers and Framebuffer 
+Objects) 
+    
+    Modify the subsection 9.2.2.2 (Multiview Images) which has been added by 
+    OVR_multiview:
+    
+    Remove from the list of restrictions ("In this mode there are several 
+    restrictions:") the following items:
+
+    "- no tessellation control or evaluation shaders (section 11.1.3.11)
+    - no geometry shader (section 11.1.3.11)"
+        
+    effectively allowing the usage of multiview rendering with tessellation and
+    geometry shaders.
+    
+    In the same list replace
+        "- in fragment shader the contents of gl_Layer are undefined"
+    with
+        "- reads and writes of gl_Layer by any shaders are undefined".
+    
+    
+Modifications to Chapter 11 of the OpenGL ES 3.2 Specification as well
+as Chapter 11 of the OpenGL 4.6 Specification (Programmable Vertex Processing)
+
+    Modify section 11.1.3.11 (Validation) by removing the following condition
+    from the list of reasons that may result in an INVALID_OPERATION error
+    being generated by any command that transfers vertices to the GL
+    (added by OVR_multiview) after
+    "Any attachment of the draw framebuffer is multiview (section 9.2.8)
+      and any of the following conditions are true:":
+
+    "- There is an active program for tessellation control, tessellation
+      evaluation, or geometry stages, or".
+    
+    
+    Modify section 11.1.3.11 (Validation) by adding the following 
+    item to the bullet point list of conditions generating an INVALID_OPERATION:
+        "The active program for the vertex, tessellation control, tessellation 
+        evaluation, or geometry shader stages contains an executable that declared 
+        a multiview view count using the "num_views" layout qualifier, but the 
+        active program for another one of these stages includes an executable that 
+        declared a different view count or failed to declare any view count."
+
+    
+Modifications to The OpenGL ES Shading Language Specification, Version 3.20.05
+and The OpenGL Shading Language Specification, Version 4.60.6:
+
+    Including the following line in a tessellation control, tessellation evaluation, 
+    or geometry shader can be used to control the language features described in 
+    this extension:
+
+      #extension GL_EXT_multiview_tessellation_geometry_shader : <behavior>
+
+    where <behavior> is as specified in section 3.5.
+
+    A new preprocessor #define is added to the OpenGL ES Shading Language
+    as well as the OpenGL Shading Language for those shaders:
+
+      #define GL_EXT_multiview_tessellation_geometry_shader 1
+    
+    In section "Input Layout Qualifiers" a new paragraph was added by OVR_multiview
+    (section 4.3.8.1 in the OpenGL ES Shading Language Specification, version 3.00.04,
+    which moved to section 4.4.1 in version 3.20.05 of the OpenGL ES Shading Language 
+    Specification and version 4.60.6 of the OpenGL Shading Language Specification).
+    
+    In this new paragraph replace
+        "Vertex shaders also allow the following layout qualifier on 'in' only"
+    with
+        "Vertex, tessellation control, tessellation evaluation and geometry shaders 
+        also allow the following layout qualifier on 'in' only".
+    
+    In the following paragraph of the same addition by OVR_multiview replace
+        "If multiple vertex shaders attached to a
+        single program object declare num_views, the declarations must be
+        identical; otherwise a link-time error results."
+    with
+        "If multiple shaders of the same type attached to a
+        single program object declare num_views, the declarations must be
+        identical; otherwise a link-time error results.
+        
+        If any vertex, tessellation control, tessellation evaluation, or 
+        geometry shader in a single program object declares a view count using 
+        'num_views', at least one shader of each type present in the program must 
+        declare a view count and all such declarations must match. If there is a 
+        missing or mismatched view count declaration, a link-time error results."
+    
+
+Modifications to Section 7.1 "Built-in Language Variables"
+    
+    Replace the following paragraph added by OVR_multiview
+        "Add the following to the list of built-in variables that are intrinsically
+        declared in the vertex and fragment shading languages:
+
+            in mediump uint gl_ViewID_OVR;"
+    with
+        "Add the following to the list of built-in variables that are intrinsically
+        declared in the vertex, tessellation control, tessellation evaluation 
+        geometry and fragment shading languages:
+
+            [[ If implemented in the OpenGL ES Shading Language ]]
+            in mediump uint gl_ViewID_OVR;
+            
+            [[ If implemented in the OpenGL Shading Language ]]
+            in uint gl_ViewID_OVR;"
+    
+
+Interactions with OVR_multiview2:
+
+    If OVR_multiview2 is supported the restriction from OVR_multiview that only
+    gl_Position is allowed to depend on gl_ViewID_OVR is also lifted from the 
+    tessellation control, tessellation evaluation, and geometry 
+    shaders.
+    
+    
+Issues
+
+    (1) This extension is based on an OVR extension, why call it EXT?
+    
+    While started as a single vendor extension, OVR_multiview and OVR_multiview2
+    are already supported by multiple vendors. This new extension also has the 
+    support from multiple vendors to be specified as EXT.
+    
+    (2) Should the functions and tokens introduced by OVR_multiview be renamed
+    to have EXT suffixes?
+    
+    No. While it is unusual to mix a vendor suffix with EXT in this "family" of
+    extensions, the main goal of this extension is to remove restrictions of 
+    OVR_multiview while keeping source code compatibiliy where possible. It is 
+    up to a successor of OVR_multiview to change the names (e.g. to revisit 
+    the unusual second underscore in gl_ViewID_OVR). The intent of this extension 
+    is to change the functionality while "inheriting" the names of the base 
+    multiview extension. 
+
+    (3) Are separable program objects with multiview allowed?
+    
+    Yes. Note that when using separable program objects, each program object 
+    can have its own multiview view count declared with the "num_views" layout 
+    qualfiier. When using separable programs, a draw-time error will occur if 
+    the view count for the programs used by the vertex, tessellation control,
+    tessellation evaluation, and geometry stages don't match.

+
+Dependencies
+
+    OpenGL 4.0 or OpenGL ES 3.2 are required.
+
+    This extension is written against the OpenGL 4.6 specification
+    (Core Profile) (February 2, 2019) and OpenGL ES 3.2 specification
+    (February 2, 2019).
+
+    OVR_multiview is required.
+
+Overview
+
+    OVR_multiview introduced multiview rendering to OpenGL and OpenGL ES.
+    
+    This extension removes one of the limitations of the OVR_multiview 
+    extension by allowing the use of multisample textures during multiview rendering.
+    
+    This is one of two extensions that allow multisampling when using 
+    OVR_multiview. Each supports one of the two different approaches to 
+    multisampling in OpenGL and OpenGL ES:
+    
+        Core OpenGL and OpenGL ES 3.1+ have explicit support for multisample 
+        texture types, such as TEXTURE_2D_MULTISAMPLE. Applications can access 
+        the values of individual samples and can explicitly "resolve" the 
+        samples of each pixel down to a single color.
+        
+        The extension EXT_multisampled_render_to_texture provides support for 
+        multisampled rendering to non-multisample texture types, such as 
+        TEXTURE_2D. The individual samples for each pixel are maintained 
+        internally by the implementation and can not be accessed directly 
+        by applications. These samples are eventually resolved implicitly to 
+        a single color for each pixel.
+        
+    This extension supports the first multisampling style with multiview 
+    rendering; the OVR_multiview_multisampled_render_to_texture extension 
+    supports the second style. Note that support for one of these multiview 
+    extensions does not imply support for the other.
+    
+    
+New Tokens
+
+    None.
+
+    
+New Procedures and Functions
+

+    
+Modifications to Chapter 9 of the OpenGL ES 3.2 Specification as well as
+Chapter 9 of the OpenGL 4.6 Specification (Framebuffers and Framebuffer 
+Objects) 
+    
+Modifications to all sections added and/or modified by OVR_multiview
+
+    Where OVR_multiview references a "two-dimensional array texture", replace 
+    this with "two-dimensional array texture or two-dimensional multisample 
+    array texture" to explicitly allow rendering to multisampled textures.
+    
+    The following is an explicit list of these changes:
+    
+    In subsection 9.2.2.2 (introduced by OVR_multiview) replace
+        "Finally, multiple layers of two-dimensional array textures can be
+        attached to an attachment point."
+    with
+        "Finally, multiple layers of two-dimensional array textures or 
+        two-dimensional multisample array textures can be
+        attached to an attachment point."
+    
+    In the additions to section 9.2.3 (Framebuffer Object Queries) replace
+        "If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_NUM_VIEWS_OVR and the value
+        of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a two-dimensional array texture..."
+    with
+        "If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_NUM_VIEWS_OVR and the value
+        of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a two-dimensional array texture
+        or a two-dimensional multisample array texture..."
+    
+    Also replace
+        "If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_BASE_VIEW_INDEX_OVR and the
+        value of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a two-dimensional array
+        texture..."

+Issues
+
+    (1) This extension is based on an OVR extension, why call it EXT?
+    
+    While started as a single vendor extension, OVR_multiview and OVR_multiview2
+    are already supported by multiple vendors. This new extension also has the 
+    support from multiple vendors to be specified as EXT.
+    
+    (2) Can this extension be used together with 
+    OVR_multiview_multisampled_render_to_texture if both are supported?
+    
+    The two extensions can be used together in the same application, but not in 
+    the same framebuffer. OVR_multiview_multisampled_render_to_texture is based 
+    on EXT_multisampled_render_to_texture, which explicitly does not permit a 
+    single framebuffer to contain explicit multisample texture types (from 
+    OpenGL ES 3.1 and core OpenGL) and "multisampled" bindings of non-multisample 
+    texture types.

+
+    OpenGL Extension #539
+    OpenGL ES Extension #320
+
+Dependencies
+
+    OpenGL 2.0 or OpenGL ES 3.0 is required.
+
+    This extension is written against the OpenGL Shading Language
+    Specification, version 4.60.5 dated July 14, 2018.
+    
+    The same shading language modifications should also be applied to the
+    OpenGL ES Shading Language Specification, version 3.20.4 under the
+    corresponding sections.
+
+    This extension interacts with ARB_texture_cube_map_array and OpenGL 4.0.
+
+    This extension interacts with OES_texture_cube_map_array and OpenGL ES 3.2.
+
+    This extension interacts with EXT_texture_cube_map_array and OpenGL ES 3.2.
+
+    This extension requires EXT_gpu_shader4 or equivalent functionality.
+
+Overview
+
+    This extension adds support for various shadow sampler types with texture
+    functions having interactions with the LOD of texture lookups.  Modern
+    shading languages support LOD queries for shadow sampler types, but until
+    now the OpenGL Shading Language Specification has excluded multiple texture
+    function overloads involving LOD calculations with various shadow samplers.
+    Shading languages for other APIs do support the equivalent LOD-based
+    texture sampling functions for these types which has made porting between
+    those shading languages to GLSL cumbersome and has required the usage of
+    sub-optimal workarounds.
+
+New Procedures and Functions
+
+    None
+
+New Tokens
+
+    None
+
+Modification to the OpenGL Shading Language Specification, Version 4.60.5
+
+    Including the following line in a shader can be used to control
+    the language features described in this extension:
+
+      #extension GL_EXT_texture_shadow_lod : <behavior>
+
+    where <behavior> is specified in section 3.3.
+
+    New preprocessor #defines are added to the OpenGL Shading Language:
+
+      #define GL_EXT_texture_shadow_lod         1
+
+
+    Add to section 8.9.2 "Texel Lookup Functions" (p. 170):
+
+    (Add variants of the texture lookup functions with supplied bias p. 170)
+
+    float texture(sampler2DArrayShadow sampler, vec4 P [, float bias])
+    float texture(samplerCubeArrayShadow sampler, vec4 P, float compare [, float bias])
+
+
+    (Add variant of the texture lookup function with supplied offset and optional supplied bias p. 170)
+
+    float textureOffset(sampler2DArrayShadow sampler, vec4 P, ivec2 offset [, float bias])
+
+
+    (Add new functions to the set of allowed texture LOD lookup functions p. 170)
+
+    float textureLod(sampler2DArrayShadow sampler, vec4 P, float lod)
+    float textureLod(samplerCubeShadow sampler, vec4 P, float lod)
+    float textureLod(samplerCubeArrayShadow sampler, vec4 P, float compare, float lod)
+    float textureLodOffset(sampler2DArrayShadow sampler, vec4 P, float lod, ivec2 offset)
+
+Dependencies on ARB_texture_cube_map_array and OpenGL 4.0
+
+    If neither ARB_texture_cube_map_array nor OpenGL 4.0 are supported for
+    OpenGL contexts, ignore references to samplerCubeArrayShadow.
+
+Dependencies on OES_texture_cube_map_array, EXT_texture_cube_map_array and OpenGL ES 3.2
+
+    If neither OES_texture_cube_map_array, EXT_texture_cube_map_array, nor OpenGL ES 3.2 are supported for
+    OpenGL ES contexts, ignore references to samplerCubeArrayShadow.
+
+Issues
+
+    (1)  Are there any other texture function and sampler combinations that are
+         missing from the specifications that might be valid combinations?
+
+         RESOLVED: Yes, as of GLSL 4.60.5 and ESSL 3.20.4, there are other
+         missing texture functions and sampler combinations that might be valid
+         but this extension does not add support for.
+
+         There is no support for Cube samplers and textureOffset family of
+         functions, and no support for Array samplers with textureProj family
+         of functions.  This extension does not add support for these functions
+         since they are 1) not related to shadow samplers and thus outside the
+         scope of this extension, 2) not yet clear if these combinations should
+         be supported at all, and 3) if support should be added then each
+         family of missing functions is deserving of its own extension.
+
+         textureGrad() is missing support for samplerCubeArrayShadow in both
+         the GLSL and ESSL specifications, and is also missing support for
+         gsampler2DArray variants only in the ESSL specification.  The
+         samplerCubeArrayShadow variant is not included in this extension
+         because not all vendors can easily support the additional parameter
+         beyond the gradients.  The missing gsampler2DArray variants in ESSL
+         are not added because they are unrelated to shadow types and thus
+         outside the scope of this extension.
+
+    (2)  The GLSL specification already contains a definition for
+         textureOffset() with sampler2DArrayShadow; does this mean only the optional
+         bias variant of this function is needed?
+
+         RESOLVED:  Yes for GLSL, but the ESSL specification does
+         not have either the non-bias or bias variants of this function so both
+         variants should be defined according to this extension.
