That may be easier, yes, but that would need either a new backend
function, or special-casing on pattern type in the xlib/xcb backends.

But a better answer to your question is that we need the workqueue
anyway.  For the scaled-font global cache for example.  Or for freeing
server resources when a surface is destroyed (which may be from another
thread at a much later time...).  So it's not like we are introducing it
just for solid-surface cache.


Also I have no idea if it makes any sense, but do we need similar stuff
in the xcb backend?  If yes, we probably should share more code between
the two.
