Function DdsDecompress

DevIL/src-IL/src/il_dds.cpp:782–833

* Assumes that the global variable CompFormat stores the format of the * global pointer CompData (that's the pointer to the compressed data). * Decompresses this data into Image->Data, returns if it was successful. * It also uses the globals Width and Height. * * Assumes that iCurImage has valid Width, Height, Depth, Data, SizeOfData, * Bpp, Bpc, Bps, SizeOfPlane, Format and Type fields. It

 * @TODO: don't use globals, clean this function (and this file) up
