SRB2/src/hardware/hw_light.c
toaster 3725203bcd Bit of a random one today, but the branch approaches completion... 
* 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]

/**
\todo
- Les coronas ne sont pas g<>er avec le nouveau systeme, seul le dynamic lighting l'est
- calculer l'offset des coronas au chargement du level et non faire la moyenne
au moment de l'afficher
BP: euh non en fait il faux encoder la position de la light dans le sprite
car c'est pas focement au mileux de plus il peut en y avoir plusieur (chandelier)
- changer la comparaison pour l'affichage des coronas (+ un epsilon)
BP: non non j'ai trouver mieux :) : lord du AddSprite tu rajoute aussi la coronas
dans la sprite list ! avec un z de epsilon (attention au ZCLIP_PLANE) et donc on
l'affiche en dernier histoir qu'il puisse etre cacher par d'autre sprite :)
Bon fait metre pas mal de code special dans hwr_project sprite mais sa vaux le
coup
- gerer dynamic et static : retenir le nombre de lightstatic et clearer toute les
light > lightstatic (les dynamique) et les lightmap correspondant dans les segs
puit refaire une passe avec le code si dessus mais rien que pour les dynamiques
(tres petite modification)
- finalement virer le hack splitscreen, il n'est plus necessaire !
