Same as most elements. Other behaviour a bit unexpected and unlikely to be useful.

+- Fix: CGUITabControl now catching EMIE_LMOUSE_PRESSED_DOWN
 - Add options for transparency node sorting algorithm.
 - CImageWriterPNG now also supports the writeImageToFile param to allow setting compressing level. 0 stays default, 1-10 for range increasing compression level.
 - Add io::IUserData which can be set in SMaterial to make it easer passing additional material values to shaders
