irrlicht/tests/transparentMaterials.cpp
hybrid 3f47f80798 Added two macros to call tests for all drivers, or for all hw drivers, with just one call. 
Added tests to check whether the driver supports the necessary features, and stop early if it does not make sense.
Fixed line endings for testXML.cpp
