Unify the dimensions for all mode/action bar icons

Having icons of all different kinds of sizes makes it difficult to get
the painting right in all cases. It definitely fails when the szsytem is
running in multi-monitor mode with different scaling factors. Unifying
the dimensions makes it possible.

This change should not cause any visual difference in a purely scaled or
unscaled screen.
