  - Examples: OpenGL3: Tweaked the imgui_impl_opengl3.cpp to work as-is with Emscripten + WebGL 2.0. (#1941). [@o-micron] 
  - Examples: OpenGL3: Made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac.
  - Examples: OpenGL3: Added error output when shaders fail to compile/link.
+ - Examples: OpenGL3: Added support for glew and glad OpenGL loaders out of the box. (#2001, #2002) [@jdumas]
  - Examples: OpenGL2: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications. (#1996)
