Reset aspect ratio on pause

When resuming the app we do resize things but the old aspect
ratio is cached, thus skipping a reset of the transform matrices
because the app thinks it is already at the correct aspect ratio.
In certain cases (changing orientation when paused) this leads to
layout bugs.
