[Mono-list] DrawingArea, DrawPixbuf, is slow?

[Peter Dennis Bartok]

Not sure I fully understood what you mean, but it sounds like you're making 
the pixel buffer bigger when the user zooms, and you're drawing everything 
scaled up? Why not just use a transformation that scales the surface? That 
way you keep the surface the same size, System.Drawing just draws it 
'bigger'.
