dolphin/Source/Plugins/Plugin_VideoDX9/Src/D3DTexture.cpp
Rodolfo Osvaldo Bogado e98a273b54 fixes for my last commit:
chage the global format of the screenshots to bmp, is correctly supported by both plugins and is faster.
reverted the changes in safe texture cache, will try to make them more stable then commit them, this should fix compilation in linux and macand error introduced in MP games
corrected all the issues commented by ector, thanks for the comments alway is good that the code is revised by others to find missed spots.
please report any remaining issue to solve them.
