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.
* Bomb sphere! Paraloopable hazard. Replaces MT_SPECIALSPIKEBALL.
* Blueberry bushes, both normal and Xmas, from patch.dta.
* BSZ tulips, also from patch.dta!
* Frozen Hillside badniks - Penguinator and Pophat.
* Frozen Hillside ice decoration!
* Fixed some big bugs with the DSZ light beams.
* Made multi-mare special stages work, in a troll way - the Chaos Emerald disappears in a puff of smoke, and the Spinbobert laughter sound plays... >:3c
* Reverted the mobjtype number changes from the source SOC/Lua, which we can do later when doing a final pass of the levels.
* State optimisation.
* Serious cruft-removal of the NiGHTS drone thinker.
* Fix the issues where the player wouldn't curl into jump in waterslides or dropping off rope-hangs.
* Tweak NiGHTS player flashing.
* Add text colour support to the titlecard font.
* Use that to make the PRESS SPIN\nMID-JUMP thing when you get all Chaos Emeralds use the titlecard font for readability.
* Fix the GOT ALL EMERALDS page not lasting the correct, extended amount of time.
* Fix that thing where flying mid-spin didn't enact autobrake.
* Modify graymap a little on Sryder's suggestion.
* [COMPLETELY UNRELATED] fix that thing where the addons menu will fail on files/paths with spaces in [/COMPLETELY UNRELATED]
* M_StartMessages when file loading goes wrong! (Determined by CONS_Alerts of warning level CONS_WARNING and CONS_ERROR happening after W_LoadWadFile has been called.)
* Now actively tries to keep your place on the menu if files are deleted between calls to preparefilemenu().
* More enums! DIR_ (for if you want to try embed more metadata in the dirmenu strings) and REFRESHDIR_ (for refreshing the menu and handling warnings).
* Handle changing size menu between calls to opendir() better.
* Don't crash on draw/enter attempt if one of the dirmenu's is null.
* Moved the addons menu to OP_MainMenu instead of MainMenu for now so it can be tested in MP without needing to mess with several menus.
* Display the amount of space used for serverinfo_pak's fileneeded on the addons menu, both visually and with a percentage.
