True, I did not mention that option (see below). Actually, even the 
panel->refresh() function optionally takes a dirty rect. A PostDirtyRect() 
function is currently not available in eeschema, so I am not subverting 

Irrespective of that, calculating the bounding box is a more difficult part, 
at least compared to the current patch (which is a few lines only). The 
current structs in eeschema do not have the corresponding properties, and the 
elements drawn can be fairly complex (hierarchical components)...

I don't know when I will have time to look at improving the performance of my 
patch. Until then, do you think the current patch should stay out (leaving 
eeschema _plain ugly_) or get in (with possible future improvements)?
