Bugfix: prevent unneeded render on pointer enter
Patch status: merged
Patch by Tony Crisci
When `focus_follows_mouse` option is on, prevent an uneeded render on pointer enter when the con is already focused. This pointer enter might be caused by entering a window decoration of an already-focused container. This extra render can cause concurrency issues when focus is set asynchronously with WM_TAKE_FOCUS.
