BGE Dome: Reducing FBO size to warped meshes.

Browse Source 
Commit 20099 started using a FBO way too big.
According to Paul Bourke this is how it's done in other Engines:

Projectors HD:
1920x1050 - buffersize = 1024; FBO size = 2048
1400x1050 - buffersize = 1024; FBO size = 2048

Projectors XGA:
1024x768 - buffersize = 512; FBO size = 1024

Now in Blender Game Engine we are using:

Projectors HD:
1920x1050 - buffersize = 1050; FBO size = 2048
1400x1050 - buffersize = 1050; FBO size = 2048

Projectors XGA:
1024x768 - buffersize = 768; FBO size = 1024

(I guess I should be committing code to the ge_dome branch instead of the trunk. I feel bad doing all those adjustments in a hurry to 2.49 final release in the trunk. That is ok, right?)
