stack images - pixmapID not supported in 2.7

[Terry Judd]

Various cool routines for capturing stack images (including offscreen 
portions) that utilised the pixmapID of the stack were posted recently. 
Unfortunately they don't work in 2.7 as pixmapID is no longer 
supported. Any other ideas on how this might be achieved or is (as it 
appears) that it!
