BGE Dome update. Spurious black seams (finally) fixed.

Browse Source 
The solution is a hack. It's a workaround for another bug (#18655).
Now it's working in all modes: fullscreen, maximized screen and gameplayer.

* small change to always set the perspective mode as true during dome mode.

Blender handles Canvas size differently when in fullscreen mode.
We are manually checking for that. Although it's a hack, it works.
