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
* M_SkyScroll optimization with still speeds; refactor background drawing
* Music (in time attack screens so far)
* FadeStrength
* HideTitlePics
* Scrolling backgrounds in Time Attack (moved F_SkyScroll to m_menu)
* Remove FUNCMATH from all void-returning functions, given GCC80 specifically complains about this case.
* Extend the length of all extant buffers to the safety threshold recommended by the compiler.
* Add void casts to WS_getaddrinfo's setting to prevent complaints about incompatible typecasts.
* Extend the charsel, face, and superface buffer sizes and writes to include the null terminator. (I didn't really want to do this because it's not even particularily NEEDED, but there was literally zero way to get around the request that I could find with multiple online searches. I tried.)
* Fix all the bugs with skin not being set properly or kept synchronised with the multiplayer setup in record attack.
* Reduce the amount of flashing on the voting screen.
* Clean up titlemapinaction so that it isn't true when you're playing
* Don't print "SPEEDING OFF TO [ZONE] [ACT 1]..." on screen if it's a titlemap - keep a nice and pretty black screen
