unify(texture): Merge W3DWater and WW3D2 texture code

[xezon]

Merge with Rebase

This change has 2 commits.

The first commit merges texture related changes from Zero Hour to Generals. It also fully merges W3DWater and W3DWaterTracks, because the water was not drawn otherwise. The second commit moves the relevant merged files to Core.

Generals gets the following things as documented by EA

• Base texture class to abstract major texture types, e.g. 3d, z, cube, etc
• Texture class abstraction
• Texture class redesign
• Render to shadow buffer texture support in texproject
• Optional custom zbuffer in texproject

Note

I did not attempty to decouple the individual EA changes, because the change complexity is too large. I simply copied everything texture related from Zero Hour to Generals as is. I think the complexit of this merge is reasonable for what it is trying to achieve.

Known Issue(s)

I only identified one issue and that is the segline, aka binary stream, missing from Lotus, Patriot. I was unable to figure out why, but I think it is ok to ignore that for now. It will very likely fix itself when we merge more of W3D. The segline does show for waypoints.

Generals World Builder fixed. Tested and Worked.

Since this moves "W3DWater" and "W3DWaterTracks" to Core, I have now also moved "Water" to Core.

Water looks good, but textures show artifacts

What map is this? I do not recognize it. The things you marked refer to terrain tiles, and that should be tested with the height map merge #1991 then. I loaded 2 official maps in Generals and I am unable to observe tiling issues.

[xezon]

I tested more and I found this is an intermediate issue with this change, it is automatically resolved with #1991.

First commit is also compiling on its own.
