- let GLInstance::Draw set the palette indexing mode.
...
This can be trivially decided based on the texture type, so there's really no need to let the higher level code deal with this.

- removed the fullbright render pass, because this is better set up as a shader option.
...
- also removed the legacy fog modes because their implementation did not mix well with the texture system - they are also not really useful to begin with.
The last fog mode will most likely also be removed once true color shading is working but that one is less of an issue.

- cleaned out some remains of the non-indexed render path.
...
All of this will be redone in the backend.

- hotfix for texture filter settings.
...
This needs to be done differently later to choose the proper clamp setting.

- cleanup of texture creation code.
...
There were several mostly pointless options complicating all of this.

- use separate textures for the palswap shade tables.
...
This creates a lot less mess than one big texture and also allows easier use of texelFetch in the server which is preferable for data textures.

wip.

- the harmless changes of the failed refactoring of the shader.

- upgraded the polymost fragment shader to GLSL 3.3 as well, removing all legacy features from it.
...
The only compatibility mode feature left is the main drawer function using glBegin/glEnd but changing that is not as urgent as the rest.
This also cleans up the fog application and adds the exponential fog mode again that somehow got lost over time.

- use explicit vertex attributes for everything.
...
No more glVertex, glTexCoord or glColor calls anywhere.

- use explicitly declared matrix uniforms.
...
The builtin matrices are no longer available in modern GLSL, preventing an upgrade of the shader.
Also perform better reporting of shader compilation errors.

- moved the animvpx shader to the backend code.
...
This removes the final access to OpenGL from the rest of the source, with the exception of the glFinish call in the swap code.

- moved the main shader and its entire uniform maintenance into the backend.

- added an engine resource file.
...
Currently this only contains the main Polymost shaders and the resources from nblood.pk3.
The latter cannot be used yet because the Build resource management system is too stubborn to add the newly added file without some changes.
It's better to refactor the entire system instead.

- initialize the GL backend in the proper place.
...
As long as there are still video mode switches this needs to be in the video mode switching function.
