The conceptual difference is that if we just reject the pitch in
wined3d it becomes part of the API, so if e.g. ddraw tries to set an
invalid pitch that's ddraw's problem. While if we don't, it's like
we're pretending that pitches like that are supported, but we really
hope nothing ever uses them, so if something sets an invalid pitch
it's wined3d's problem to make it work somehow. The distinction is of
course a bit artificial because everything is under our control, but
the former seems more proper to me.

Possibly, although at least ddraw_surface_create() will already print
an ERR if wined3d_texture_update_desc() fails.
