Yes, to put a per output workarea in the CompOutput struct and have
updateWorkareaForScreen update them sounds like a good idea.

It should work OK when we have per output workareas which are computed
using the data from each windows _NET_WM_STRUT_PARTIAL hint.

We can probably do that eventually but we still need to keep the
_NET_WORKAREA hint updated properly.
