* Fixed an unused variable warning in lua_skinlib.c.
- fixed post-level cutscenes playing when you get game over in MP (still kinda on-topic)
Also with apologies to MI:
- golden egg statue mode for tutorial, since the grey doesn't contrast enough with the blue and lime green
- fixed closed captions for replaced player sounds being incorrect
- fixed closed captions overlapping tutorial text
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.
- Split MF2_DONTDRAW into MFD_DONTDRAWP[1-4], also replaces MFE_DRAWONLYFORP[1-4].
- Split MF2_SHADOW into MFD_FULLBRIGHT and MFD_TRANS80. I also added an entire spectrum of options for transparency & brightness overrides, since I've found myself wishing for stuff like that before.
- Tethering was updated for it's client-sided drawing to apply to splitscreens too.
- Removed cv_transparency.
The transparency overrides don't seem to work yet (obvious on things using MFD_SHADOW), just running out of time to look into it so I'm pushing what I have.
