gEDA-user: Drawing with Cairo -- zooming, panning demo

[Stefan Salewski <mail@xxxxxxxxxxxx>]

I just put a small demo for drawing with Cairo into a GTK drawing area
on my page:

http://www.ssalewski.de/PetEd-Demo.html.en

It supports zooming, scrolling and panning. It is written in Ruby, only
260 lines of code including some comments.

Maybe it is useful for people working on footprints wizards or similar
small tools. Panning/scrolling is not really fast, it is not optimized
to keep it simple. (Maybe we should copy part of the content instead of
complete redraw.)

Maybe such a minimal demo already exists -- have not found it.  

Best wishes,

Stefan Salewski
