"The extra if" in Wayland ConfigureWindowGeometry

[icculus]

The extra if guard won't work , as ConfigureWindowGeometry() needs to be always be called from this function to set some initial window properties (making it conditional was tried and caused problems). To change this would require some changes in Wayland_CreateWindow(). Nothing complicated, but it's better left for a separate pull as it's not directly related to this issue.
