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.

Unlikely we ever support conversions with compressed image format.
Define is a bit ugly I guess, but nicest way I could think off.
Can probably be used in some image writers as well, have to check which support/don't support compressed formats first.
