* the parser read numbers with leading zeros as octal, which is not wanted here
* texture lookup by file name must be forced for root directory entries.
Using the palette to apply fog is just far too broken and cannot be kept in check with all the hacks the Build engine allows.
This only works if all elements on screen use the identity translation lookup which is basically never the case.
Real fog, on the other hand, can easily be applied to everything.
The original tiles are all 15 pixels tall, but depending on the games can vary in their true height, so use CheckRealHeight on them to get their true dimensions.
Fixes#250
In these cases the palette needs to be ignored and the base version picked. The proper handling for this case was undefined, working in some cases and not in others.
Fixes#247
This ensures that callback indices are consistent. Runtime registration as performed by NBlood has undefined order and will make savegames non-transferrable.
The recent changes for replacing fonts with hires versions made the paletted handling kick in, although the voxel textures are not suitable for that.
Fixes#178
This essentially removes the tiny font which is simply too small to ever be able to receive a proper international extension from the equation for localization because the level name display was the only remaining relevant content using this font.
The only other screen where this font is still being used to draw text requiring translated content is the multiplayer summary which will have to be redesigned anyway if multiplayer becomes functional again.
Apparently this is needed by some hires packs to fudge the sprite offsets.
Fortunately, setting sprite offsets is the only thing this was ever used for so it's relatively uninvasive.
Avoid passing this anywhere in the client code. It should only be set right before rendering the 3D view and the only code using the base palette should be the 3D renderer and hud_drawsprite.
Also make the palette override CVARs 3D view only in debug mode.
Also added support for creating indexed textures directly into CreateTexBuffer, where this functionality can be shared.
As an added plus, brightmaps are working again, this time with less hackery.
