Fix usable area calculation

Browse source 
Currently if a surface with exclusive zone is created prior to regular
surfaces, the size of the exclusize zone does not affect the usable area
for regular surfaces. This for example results in notifications being
rendered over the statusbar.

This commit fixes the issue by handling the surfaces with exclusive
zones first.

Fixes #420.
