Does this happen much in practice? Do you have performance numbers?
The patch doesn't really make sense in its current form.
surface_download_data() is meant for downloading the data from the
texture. If that's not what you want, don't call it. (Also, does this
actually work? It looks like it's just reading from the current
drawable.)
