panel: Consider visibility changes for solid style

Browse Source 
We currently assume that window state changes are accompanied by an
allocation change (triggered for example by the minimize animation).
However this misses the case where a window actor is simply hidden
without any transition, as is the case with the 'show-desktop' action
for instance, so start tracking plain visibility changes as well.
