Rewrite the whole project for GL4+. I figured if we removed the limitation of a legacy rendering API we could improve things a bit. With GL4+ we can do unsigned integer math in the shaders. This allows us to upload a direct copy of the real3d texture sheet, and texture directly from this memory given the x/y pos and type. This massively simplifies the binding and invalidation code. Also the crazy corner cases will work because it essentially works the same way as the original hardware.
...
The standard triangle render requires gl 4.1 core, so should work on mac. The quad renderer runs on 4.5 core. The legacy renderer should still work, and when enabled a regular opengl context will be created, which allows functions marked depreciated in the core profiles to still work. This will only work in windows/linux I think. Apple doesn't support this.
A GL 4.1 GPU is now the min required spec. Sorry if you have an OLDER gpu. GL 4.1 is over 12 years old now.
This is a big update so I apologise in advance if I accidently broke something :]

Fix new 3D engine texture2DLod function missing error on Linux/MESA. MESA requires needed extensions to be explicitly declared in code otherwise it will not enable them.

The translator map seems to work with paletted colour values too, and the result is not clamped. Colours are passed to the GPU as unsigned bytes to multiplying by 16 will overflow, so we do the logic in the shader. If we passed floats we could skip the shader logic.

Technically backface culling should cull polys when the dot product = 0, since when it equals 0 the polys is perpendicular to the camera and thus invisible. When you complete sega rally2 (if you can get that far lol) the champagne is invisible. The reason is because all the face normals are 0. So when multiplied by the model matrix they are still 0 and get culled. Tweaking the condition to only cull polys when greater than 0 fixes this, and allows these 'bad' polys to render as they do on the model3.

Fade out microtextures with higher textures LODs. Fixes incorrectly applied microtextures in LA machineguns.

Correctly emulate the real3d pro-1000 texture modes in our shader.

Quad rendering engine. Set QuadRendering = 1 in the ini file to use, or -quad-rendering at the end of the command line to use.
