Until now each subclass of FTexture had to implement the entire span generation itself, presumably so that a few classes can use simpler structures.
This does not work if a texture can have more than one pixel buffer as is needed for alpha textures.
Even though it means that some classes will allocate more data now, it's the only way to do it properly.
In addition this removes a significant amount of mostly redundant code from the texture classes.
- added alpha texture processing to all converted classes
As of now this is not active and not tested.
Note that as part of the conversion even those textures that were working as alphatextures will not look correct until the higher level code gets adjusted.
Most of those which still rely on ZDoom's own definition should be gone, unfortunately the code in files that include Windows headers is a gigantic mess with DWORDs being longs there intead of ints, so this needs to be done with care. DWORD should only remain where the Windows type is actually wanted.
Fix crash due to dc_source2 not always being set
Add r_lod_bias to control mipmap selection
Improve LOD calculations to take the U texture coordinate into account
- These require manual detection and overriding of the scaling factors to
0, because a right shift of (32-0) bits wraps around to 0 and results in
no shift at all rather than leaving the register zeroed out.
- Fixed: If a part of a multipatch texture is replaced by a HIRESTEX
version, the original patch must not be deleted, since the multipatch
texture still needs it for compositing.
ignored the Y locations of patches drawn on two-sided midtextures and always drew them at the
top of the texture. Added a compatibility flag.

only has 64 entries and is not precise enough. It now uses finesine instead.
- fixed: When compositing a multipatch texture any patch that is a multpatch
texture itself and contains rotations may not be composited directly into
the destination buffer. This must be done with an intermediate buffer.
- Fixed: Drawing a slider in the options menu did not scale the x-coordinate.
- Fixed: If the alt HUD had to draw negative numbers the minus sign was misplaced
due to incorrect texture coordinate calculations.
- changed option menu scaling for widescreen modes so that it doesn't scale down
so quickly.
- made some error messages in DECORATE that don't affect the parsing non-fatal
so that the parser can continue to find more problems.

for true color. Instead of using a clipping rectangle on the destination it
tried to alter the source offsets which produced incorrect results for
mirrored or rotated patches.
