+ Version 1, June 7, 2018
+
+Number
+
+ 302
+
+Dependencies
+
+ OpenGL ES 3.1 is required, for FramebufferParameteri.
+
+Overview
+
+ This extension defines a new framebuffer parameter,
+ GL_FRAMEBUFFER_FLIP_Y_MESA, that changes the behavior of the reads and
+ writes to the framebuffer attachment points. When GL_FRAMEBUFFER_FLIP_Y_MESA
+ is GL_TRUE, render commands and pixel transfer operations access the
+ backing store of each attachment point with an y-inverted coordinate
+ system. This y-inversion is relative to the coordinate system set when
+ GL_FRAMEBUFFER_FLIP_Y_MESA is GL_FALSE.
+
+ Access through TexSubImage2D and similar calls will notice the effect of
+ the flip when they are not attached to framebuffer objects because
+ GL_FRAMEBUFFER_FLIP_Y_MESA is associated with the framebuffer object and
+ not the attachment points.

+ Accepted by the <pname> argument of FramebufferParameteri and
+ GetFramebufferParameteriv:
+
+ GL_FRAMEBUFFER_FLIP_Y_MESA 0x8BBB
+
+Errors
+
+ An INVALID_OPERATION error is generated by GetFramebufferParameteriv if the
+ default framebuffer is bound to <target> and <pname> is FRAMEBUFFER_FLIP_Y_MESA.
