window: Don't needlessly sync parent and geometry

When a toytoolkit client redraws, the toolkit syncs the parent and
geometry. If a client redraws often (such as the terminal drawing a huge
amount of output), this can spam the compositor with requests and may
result in the client's eventual being killed.

We don't need to send requests for changing the geometry or parent if
these haven't changed. So remember the last geometry and parent, and
update them only if needed.
