We no longer have to maintain this standard manually. I actually suggest making booster sectors use the lightlevel of their surrounding sectors so that only the booster itself glows.
(OGL support is commented out, since it conflicts with sal-lighting and should probably be done there)
"precipprops" lets you create a new precipitation type by picking a mobj type to use, how many random states it has, and flags for effects such as thunder/lightning. Seesound on the mobj type sets an ambient sound (like rain drops) and mass sets the sound's frequency in tics. This could open up the possibility for SOC/Lua Weather options later.
I've tried to make this so it almost never under-compensates, and over-compensates very little where possible.
I don't think it's 1:1 to software's current behaviour, and probably never will be due to software being very strange.
- Add modeltilt variable, for more manual control of the model tilting. By default this just copies standingslope, but doesn't get cleared in the air.
- Shadows & trailing bananas now tilt to match the ground they are on.
- Rocket Sneakers & afterimages now tilt to match the player's current orientation.
* Ranges between full brightness to half-brightness (50% of fullbright effect).
* Has both software and GL support (I think - GL needs to be doublechecked, but I think it's just GL being murky in general).
* Used by Rings.
* Backport FF_GLOBALANIM and FF_RANDOMANIM extensions to FF_ANIMATE from 2.2.
* Rings use the former instead of their own hacky solution to the problem.
* Also backport FF_VERTICALFLIP, because why not.
* Inverts sprite relative to gravity. I remember wanting this for the flipped death sprite for Jawz, but then Oni drew his own frame for that, so it doesn't matter.
* Refactor vissprite struct a tad, given I did so in internal where I pulled most of these improvements from.
* Should be no in-game affect; let me know if you notice any regressions.
