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.
* Add more context clues to his fight, including an indicator for which laser attack is being used after chargeup.
* Make missiles able to vectorise him.
* Add another laser orb attack - vertical slice - and change the laser orb sequence to accurately reflect that horizontal is the hardest of the ones in 2.1.
* Optimise TC_BLINK, and fix an issue with TC_ALLWHITE that somehow avoided coming up in testing.
* Fix colorized bosses losing their colorization when flashing, by forcing TC_ALLWHITE.
* Port across the additional colour translation maps, including mobj-level support for "colorized" objects.
* Make Fangboss and both Metal Sonic objects greyscale if, on spawn, there is a player in the game who is not a spectator whose skin is that character.
* Allow bosses with MF_GRENADEBOUNCE to opt out of the MF2_FRET colour-flashing tomfoolery, and give this flag to Fang.
- Name each frame either SPR2_**** or SUPER**** (where **** is the 4-character name)
- If the name is 3 characters, '.' is accepted as a substitute for the '_', but a space/absent isn't (for tool-related reasons).
- Adds a big sprite2 index array to all models, even non-player ones. Sorry!
* Made MD2 frame interpoleration only work across the same spriteset (and sprite2set).
* Made MD2 frame interpoleration happen when there's less than a quarter of a second between frames, as opposed to the hardcoded specific animation disabling.
* Fixed sprite2-related typo in dehacked.c.
I added similar checks for the other num* but it seems some MD2s break the other limits without knowing anyway ...so I've commented these checks out for now, unless we have further discussion regarding them later on
* flips the sprite ala MFE_VERTICALFLIP except you don't need to flip the direction of gravity for the object just to draw upside down
* stacks properly with reverse gravity
* Several new supercolours.
- SKINCOLOR_SUPERSILVER1-5 (for fun) - "Silver"
- SKINCOLOR_SUPERPERIDOT1-5 (nyeheheh) - "Peridot"
- SKINCOLOR_SUPERCYAN1-5 (for fun) - "Cyan"
- SKINCOLOR_SUPERPURPLE1-5 (for fun) - "Purple"
- SKINCOLOR_SUPERRUST1-5 (mecha/metal sonic) - "Rust"
- SKINCOLOR_SUPERTAN1-5 (shadow/silver the hedgehog) - "Tan"
* SKINCOLOR_SUPER1-5 renamed to SKINCOLOR_SUPERGOLD1-5, one index for darkest is changed - "Gold"
* SKINCOLOR_TSUPER1-5 renamed to SKINCOLOR_SUPERORANGE1-5, ported properly to the new palette - "Orange"
* SKINCOLOR_KSUPER1-5 renamed to SKINCOLOR_SUPERRED1-5, ported properly to the new palette - "Red"
* new S_SKIN attribute - supercolor - uses an entirely different function to get the names (R_GetSuperColorByName instead of R_GetColorByName)
* a fun little secret - typing "god on" in the console whilst super makes the player hyper (visual only, no sparkles - just rainbow flash) - can be removed if no fun is allowed
