Zack Middleton c9d12aa3f3 Add common OpenGL version parsing + OpenGL 3 fixes 
- Parse OpenGL version in sdl_glimp.c to share with both renderers.
- Add GL_VERSION_ATLEAST(major, minor) macro.
- Get address of glGetStringi if using OpenGL 3.
- Fix glConfig.extensions_string when using GL3 core context in
opengl2 renderer.
- Make opengl1 renderer's gfxinfo support qglGetStringi too.

Zack Middleton 59b1262b82 Fix floating point precision loss in renderer [part 2] 
Fix floatTime using float precision instead of double using GCC.
Fix R_BindAnimatedImage to be in sync with function table.
Fix vertexDeform bulge, vertexDeform normals, noise wave function
at high level time.

Revert unnecessary float -> double conversions.

Zack Middleton 30fdd88c9f Fix floating point precision loss in renderer [part 1] 
Patch for https://bugzilla.icculus.org/show_bug.cgi?id=5931 by
Eugene C. from 2013 plus recent fix for tcMod rotate.

I merged the changes into the OpenGL2 renderer though the fix for
tcMod turb doesn't translate.

SmileTheory d549b642bc OpenGL2: Use an OpenGL 3.2 core context if available. 2017-07-13 12:03:10 -07:00
Zack Middleton 904bbc1a8f Allow more than 32 surfaces in skin files 
Models don't have a surface limit; skins shouldn't either. Some player
models require more than 32 surfaces since vanilla Quake 3 did not
enforce the limit.

Skins are now limited to 256 surfaces because having no limit would
require parsing the skin file twice. The skin surfaces are dynamically
allocated so it doesn't increase memory usage when less surfaces
are used.

Zack Middleton 60d28722ef Remove unfinished OpenGL display list code 
It seems unlikely anyone is going to do anything with this aside from stub
it out in OpenGLES ports.

SmileTheory b1821e303d OpenGL2: remove lightmap support from generic glsl shader.

Zack Middleton 75cce50a9c Don't load external GLSL files by default 
External GLSL should probably only be used for development testing,
not released products. The GLSL files are tied to the code, and the
code changes some what often.

Fixes using OpenArena 0.8.8 which has incompatible GLSL files in a pk3.
