Add floor32, ceil32, round32 compatibility functions for burnings renderer.
To avoid changing burnings now those functions have no IRRLICHT_FAST_MATH anymore, there's a new header irrMathFastCompat.h which has ..._fast functions doing the old behavior. With the troubles they have documented. I changed burnings to use those functions throughout. Or as much as possible... Burnings probably also uses classes like SColor which also have functions using those, but I don't plan to adapt them. Maybe IRRLICHT_FAST_MATH should be a flag exlusive to burnings in the future, I don't think it makes much sense otherwise anymore (it often expects 32-bit asm). git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6012 dfc29bdd-3216-0410-991c-e03cc46cb475
