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

Base for area is the image, which means:

- The original clipping area when the texture is scaled or there is no texture.
|
|
- The source-rect for an unscaled texture (but still restricted afterward by the clipping area)
|
|
Unlike normal clipping this does not affect the gui-children.
