use GetWindow()->Refresh() in Wayland only 

Some people are reporting stuttering, and @retro-wertz tested both
DrawArea() and Refresh() on wxgtk3 under xorg and found that the
Refresh() method produces more stuttering.

Change the compile check for wxgtk2 to a runtime check for wayland, and
use Refresh() under Wayland only.
