[PATCH 1/5] wined3d: Support custom pitches in wined3d_surface_update_desc (try 3).

[Stefan Dösinger]

Try 3: Fix the size calculation, use height * pitch.

Try 2: Drop the first patch and always calculate the surface size based
on width, height and format to make sure a format with a non-zero size
is set.
