(oddly enough, this actually revealed some secret file dependencies previously included via r_things.h! I also needed to include d_player.h in r_skins.h itself it seems)
Also:
* SPR2_XTRA - instead of defining lumpnames in S_SKIN, those kinds of assets can just be bundled into the spriteset. Required for ending cutscene stuff, I guess, but also done for HUD life icon and character select image (aside from Sonic&Tails, still SOC'd in).
* Minor oversights in SPR2 support corrected.
* Better evaluation, featuring ending assets.
* Intro has warping-in blackrock, reusing ending assets.
* Cutscene text now supports lowercase (intro and custom).
* Disable the asset-fucking "gamma correction" I put in over two years ago when implementing colour cube. (This is the only thing I could move into another branch if you MUST, but it's basically invisble in the diff so w/e.)
* Don't blank the screen if the top left pixel of a screen-covering patch is transparent. (Checked via nonzero topdelta for first column)
Bugs:
* OPENGL ONLY: The first ~20 frames of both endings are fucked. A little help here? Might be HWR_DrawFadeFill's fault, which I just created. OR it could be in f_finale, but I doubt it, since it doesn't appear in Software.
* Draw background over titlemap
* HIDEBACKGROUND to show titlemap
* Specify NOMUSIC or IGNOREMUSIC (to not change music)
* Linedef execs implemented for tree hierarchy, including bubbling (NOENTERBUBBLE/NOEXITBUBBLE)
* Specify ENTERWIPE and EXITWIPE
* Menuid hierarchy fixes (Control mapping, joystick setup)
* Time attack handling fixes
* Specify custom wipes on runtime for D_Display and P_SetupLevel (for titlemap)
* Allow for forcing and skipping a wipe
* Wipe utility functions F_GetWipeLength and F_WipeExists
Used instead of pLocalPalette when attempting to determine objective truths, such as "the colours of this gif without color profile modification" and "what indicies should this colormap remap to".
Also, made f_wipe.c's paldiv only get calculated once.
