Hi Rich,

The fUse24Bpp was not in your previous patch. I think this does not make
sense as a local static variable, as different surfaces could have
different needs regarding 32bit or 24bit drawing. That could happens (in
Firefox), if you surface was for onscreen display, the other for printing).
I think you should make that a flag of the surface structure instead.

Everything looks good to me on a quick glance. :-)
