* Combined members of TextureHeader_t and RTechTextureInfo_t.
* Renamed 's_pRTechBytesPerPixel' to 's_pBytesPerPixel' and declared const.
* Renamed 'dxgiToRPakFormat' to 's_DxgiToTxtrTable' and declared const.
* Renamed 'rpakToDxgiFormat' to 's_TxtrToDxgiTable' and declared const.
* Moved 'g_DxgiToTxtrTable' and 'g_TxtrToDxgiTable' to 'texture.g.h'.
* Moved 's_pBytesPerPixel' to 'texture.g.h'.
* Fixed defect where we used the [] operator on a std::map that should be const (s_TxtrToDxgiTable), replaced with the const version of std::map::at.
This commit implements missing material error logging.
When a material does not exist, it will get replaced with an error material, we log which material is missing, and with which error material it gets replaced with.
This commit also comes with some updates regarding the CMaterialGlue class, and some new types used by this class from the RePak project.
