DIB section improvements; UpdateDIBSection has been replaced with
LockDIBSection and UnlockDIBSection, for improved thread safety.
DIB_Status_* is now driver-independent, and there's a new
DIB_Status_AuxMod. Better handling of DIB surfaces with nonstandard
pitch. Slight optimization of DIBsection->display BitBlt.
