hi @raysan5, I ran rlgl.h into some "typo checking" program(basically a JetBrains IDE), and here are all the things that the program was able to spot and fix. as my English isn't really well I would like it if you could check that I didn't make any mistakes in the typo fixing...

* OpenGLES 2.0 support on PLATFORM_DESKTOP

* exmples raylib_opengl_interop desktop GLES2 support

* rename gles2.h -> glad_gles2.h

* Use const for pointer float array

* missed a definition

Reviewed formating to follow raylib coding conventions.

rlCullFace sets the face culling mode to RL_FRONT or RL_BACK which correspond to GL_FRONT and GL_BACK respectively.

As generation is done in software, it's up to the user to do it. `ImageMipmaps()` is already provided for reference.

* [rlgl] Check for extensions before enabling them

* Shift to glad on macOS

* #undef CORE_OPENGL_33

* Remove version hack and fix ASTC compression assumption

* Remove loader from glad

* Use GLAD_MALLOC/FREE instead of malloc/free

* More explicit extension checking

raylib library tries to avoid `long long` usage. Several SSBO functions have been reviewed (including some renames for consistency) to minimize `long long` type usage.

Updated version to `rlgl 4.2`

rlGetGlTextureFormats was expecting unsigned int, corrected variables according to that.
