irrlicht/source/Irrlicht/CGUIImage.h
cutealien ffd7b63af0 API BREAKER: Replacing defines in irrTypes.h which are conflicting with c++ reserved identifier rules.
C++ has undefined behavior for identifiers starting with __ or with _ followed by an uppercase letter.
We still have many more (in IrrCompileConfig.h and in all header-guards), will likely replace those later as well.
As a workaround for users which might use irrlicht defines in their code, I've added the header irrLegacyDefines.h
Including that allows to continue using old defines for a while - or make it easier to have code which compiles 
with old and new Irrlicht library versions.
