As a bonus this already fixes several bugs caused by the botched texture scaling implementation the original texture manager came with.
System cursors are currently disabled because they rely on functionality that needs to be moved to different classes.
- Slightly improve how softpoly processes portals
- Pass the vertex transform matrix via a command rather than being part of the drawer args
- Improve zbuffer drawers in the software renderer
- Misc model rendering fixes
This was a bad idea from the start and really only made sense with DirectDraw.
These days a FrameBuffer represents an abstract hardware canvas that shares nothing with a software canvas so having these classes linked together makes things needlessly complicated.
The software render buffer is now a canvas object owned by the FrameBuffer.
Note that this commit deactivates a few things in the software renderer, but from the looks of it none of those will be needed anymore if we set OpenGL 2 as minimum target.
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.
For some files that had the Doom Source license attached but saw heavy external contributions over the years I added a special note to license all original ZDoom code under BSD.
This was very poorly done without ever addressing the issues a composite render style can bring, it merely dealt with the known legacy render styles.
The same, identical code was also present in two different places.
The oversight that AlterWeaponSprite overrode even forced styles was also fixed.
OpenGL is not implemented yet but with the problems eliminated should be doable now.
- moved testcolor and test fades into SWRenderer files.
These CCMDs work by hacking the default colormap and were never implemented for hardware rendering because they require many checks throughout the code.
(Is there anyway to tone down GCC's warning level? It outputs too many false positives for potentially uninitialized variables in which the genuine errors get drowned.)
