BRUH MOMENT

I would like to use higher dashmode values for extra leniency, the jet fume kicks and screams when this happens.

Mhm hmm...

This changes how blend modes render, and includes fixes.

This fixes the texture of the floorsprite sometimes facing the wrong way, since plane rendering can change the view angle.

- PF_NOJUMPDAMAGE no longer affects height at all (you're welcome katsy).
- Characters with SF_NOJUMPSPIN will only use spinheight when panim is PA_ROLL. They cannot enter gaps when jumping with spinheight, unless also spinning or gliding.
- All other characters use spinheight when panim is PA_JUMP or PA_ROLL. They can enter gaps when jumping with spinheight.

- players with SF_NOJUMPDAMAGE but *not* SF_NOJUMPSPIN now always use spinheight while jumping (i.e. even with PF_NOJUMPDAMAGE), as long as their panim is PA_JUMP or PA_ROLL
- players with SF_NOJUMPSPIN no longer use spinheight while jumping (but,)
- PA_ROLL is now an acceptable condition for using spinheight (but not for entering gaps, e.g. S3K shields will shrink the hitbox but not allow gap entry on their own)
- flying players now only use spinheight if they do not have SF_NOJUMPSPIN (you're welcome, EggpackRE)
- players with neither SF_NOJUMPSPIN nor SF_NOJUMPDAMAGE use the same conditions as in 2.2.9 prerelease, i.e. use spinheight and can enter gaps unless they have PF_NOJUMPDAMAGE

(Apparently Kart made this exact fix 2 years ago and it was never backported?)

Fixes culling issues in CEZ2 skybox

This was causing a buffer underwrite too. Lovely.
