sorry about the mixup earlier regarding the use of ShadowStage vs. 
ShadowEngine.
Viewports are supposed to allow the user to specify the size either in 
pixels or relative coordinates (values > 1 are considered pixels, values 
in [0,1] are relative) - that's the reason for the lines you commented, 
the code wants to use pixels.
However, by the time the ShadowEngine is reached, the viewport 
coordinates should have been normalized, which oddly is not happening in 
your case on the render servers. I believe that is the real problem here 
and will see if I find where things go wrong. Thanks for tracking things 
down to viewport sizes being off!

	Cheers,
