Usually surface pitches are either 4 or 8 byte aligned(depending on the API 
and pool). I recommend to write some tests for this. The most likely 
problematic formats are D3DFMT_P8, any 16 bit format like R5G6B5 and 24 bit 
R8G8B8. Maybe you're supposed to honor the pitch_or_linear_size member of the 
DDSURFACEDESC.
