I'm developing a scene with the following camera statement, and the 
output is different when I turn radiosity on or off. With radiosity on 
the camera doesn't rotate around its axis like it should.

#declare Camera_Mode		= 5;			// 0 to 8
#declare Camera_Diagonal	= cosd(45);
#declare Camera_Vertical	= -135 + 22.5;		// 135 + 22.5

Scratch that. It was a bug in my code.
