Since unfortunately this cannot be set as a general default, let's at least make it as easy as possible to disable that panning+scaling madness without having to edit the texture data.

This particular case incorrectly factored in the sidedef's scaling factor for how to calculate the offset.
Fortunately this is a very rare case - a quick check yielded no maps depending on it.
Should any map surface that depends on this bug a compatibility option may be needed but it doesn't seem likely that this may be the case.
This reuses the FTexCoordInfo class the hardware renderer had been using to calculate wall texture offsetting.
The software renderers still need this sorted out to bring them in line with the rest of the code, though, but they do not have this code sufficiently well organized to make this a straightforward task.

This was done mainly to reduce the amount of occurences of the word FTexture but it immediately helped detect two small and mostly harmless bugs that were found due to the stricter type checks.
These cannot be done with the regular textures so there needs to be an option to create more than one native texture per FTexture. For completeness' sake there is also the option now to create a paletted version of a texture if the regular one is true color. This fixes a long standing problem that translations were not applied to non-paletted textures.
* Instead of using the red channel it now uses the grayscale value. While slower in a few situations, it is also more precise and makes the feature more useful.
* For paletted textures do not use the index as alpha anymore but the actual grayscaled color. This is again to make the feature more consistent and useful.
* To compensate for the above there is now a list of hashes for known alpha textures in patch format, so that they don't get broken.
* IMGZ is now considered a grayscale format. There's only two known textures that use IMGZ for something else than crosshairs and those are explicitly handled.
* several smaller fixes.
* the actual color conversion functions for paletted output are now consolidated in a small number of inlines so that future changes are easier to do.
Note: This hasn't been tested yet and will need further changes in the hardware rendering code. As it is it is not production-ready.
Now it is no longer necessary to provide specially set up textures for rendering shaded decals, they can use any PNG texture now that contains a proper red channel.
Handling of the alPh chunk has been removed as a result as it in no longer needed.
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.
