Length of DataStream in d3d9 #631

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
In Direct3D9::Surface::LockRectangle, the length of the DataStream is 
computed by:

int lockedSize = lockedRect.Pitch * Description.Height;

But for DXT formatted surfaces the pitch is in rows of blocks, not pixels, 
so height should be something like: (height + 3) / 4;

This probably affects volumes as well, but I haven't checked.  I also 
haven't looked at d3d10/11.

Looks like DXT is limited to 2D, so Volume is fine. Am ignoring this in 10/11 
for the time being.
