Usually something like __IRR_SOME_GUARD_INCLUDED__ replaced by IRR_SOME_GUARD_INCLUDED. Removing underscores at the end wasn't necessary, but more symmetric (probably the reason they got added there as well). While this touches every header it shouldn't affect users (I hope). Also a few whitespace changes to unify whitespace usage a bit. And a bunch of spelling fixes in comments. git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6252 dfc29bdd-3216-0410-991c-e03cc46cb475

will be set as parameter in the callback method when calling
|

OnSetConstants(). In this way it is easily possible to use the same

callback method for multiple materials and distinguish between them

during the call.

\return Returns the number of the material type which can be set in
|
|
SMaterial::MaterialType to use the renderer. -1 is returned if an
|
|
error occurred. -1 is returned for example if a vertex or pixel shader
|
|
program could not be compiled, the error strings are then printed out
|
|
into the error log, and can be caught with a custom event receiver. */
