KUDOS to you, this looks great. If you don't have time, I'll eventually
see if I can port it to the GTK Hid. There may be a GTKish way to make
the XRender calls, I'll investigate if I do the porting.

I was looking at some "wow isn't our product fantastic" videos from
commercial EDA vendors recently, and they have similarly fancy previews.
They use 3D / GL / DirectX of course, which is something Peter B and I
have mused over (but done no coding for).

Theory has it, that writing a GL HID based on either GTK or Lesstif
shouldn't be too hard, we'd just need to turn arcs etc.. into polygons.

I really liked your GIMP effects, and it would be sweet to have a
preview mode like that.

Best wishes,

Peter ("yes, I do fall for 'bling' sometimes") Clifton.
