Le Philousophe 7794de5e5e GRAPHICS: OPENGL: Allow sscanf_s for GLAD 
It is properly guarded so it won't bring any portability problem and the
file is autogenerated so this avoids to patch the file.

Le Philousophe a31ea07f82 Revert "GRAPHICS: OPENGL: Disable usage of sscanf_s" 
This reverts commit 5040e1129d.
Instead of modifying an autogenerated file, patch around it.

Eugene Sandulenko 5040e1129d GRAPHICS: OPENGL: Disable usage of sscanf_s 
This follows the earlier commit that added this symbol to forbidden.h
The code in glad.h is not using any features of sscanf_s, e.g.
sizes for the provided strings for safety, so it is not clear
why are they using it. Perhaps because it is declared "safer"

Le Philousophe 42fa87acea GRAPHICS: OPENGL: Don't try to use GLAD aliasing for shaders 
Aliasing doesn't cover all the functions we use.
In addition, old GLSL 1.00 doesn't support the #version stance.

Le Philousophe 03a53b1a1e OPENGL: Fix GLSL version parsing 
Some old GLES2 implementation did have a different version prefix.
Be more relax like almost everyone and look for the first digit to start
parsing.

Le Philousophe 306ca933d4 OPENGL: Use GLAD version when available and check functions before use 
When GLAD fails to parse version, glGetError is null and raises a
SIGSEGV.
Current version of GLAD has a bug while parsing extensions so there is a
workaround here which should disappear when it's fixed.

Le Philousophe 8569296384 OPENGL: Detect framebuffer support using GL_ARB_framebuffer_object 
We use functions from GL_ARB_framebuffer_object extension and not from
GL_EXT_framebuffer_object where functions are suffixed by EXT.
This avoids crashes on implementations supporting only the EXT version.

Le Philousophe c9b4949746 AMIGAOS: Improve shader compatibility 
OGLES2 doesn't support uniform booleans so we use macros to make it use
integers in this case. For other platforms, this change should be a
noop.
OGLES2 doesn't like float suffix for constants, remove it as well.

Thunderforge fd129ebc0c JANITORIAL: "Mac OS X" and "OS X" to "macOS" in comments 
Apple's desktop operating system was formerly called "Mac OS X" and "OS X", but since 2016 it has been called "macOS" (starting with version 10.12).

Changing across all comments and documentation to use this current terminology, except in cases where the historical versions are explicitly referenced. No code changes are made; we should consider changing those in future PRs.
