BGE Dome: Reducing FBO size to warped meshes.
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?)
