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.
