I'd be grateful for this if it applies to the general case, not only 
layouts with background. I tend to do tedious work like routing on the 
train. However, my laptop is a bit dated (900 MHz pentium, no graphics 
accel). Pan and zoom does a bit of stammering compared to my desktop. 
With full polygon draw even my one year old desktop feels a tad 
unresponsive.

A screenshot of a typical layout of mine can be seen at
