Did you notice that the images are not 800x600 when selecting 800x600?
This is because the code only outputs the relevant schematic, without
the blank border that libgdgeda being in the libgdgeda output.

Thanks for the changes. I think that picture and PNG support are
complete now.

I would not use it this way. You can use GTK_MAJOR_VERSION and
GTK_MINOR_VERSION which are defined by GTK. If you are using a widget
available only from version 2.6, then you can write something like this:
#if ((GTK_MAJOR_VERSION > 2) || \
((GTK_MAJOR_VERSION == 2) && (GTK_MINOR_VERSION >= 6)) )
<code for GTK version 2.6>
#endif
In fact, I am using them in a file load/save window replacement (using
the GTK file chooser), and they are working great.
If you are curious, I have the new file chooser working, but I'm stuck
again trying to get a preview of the file for the file chooser.... I
think we really need some way to get a pixbuf from a toplevel structure
_without_ defining or using a drawing_area (which needs to be visible)
and totally unaware of windows or drawing_areas defined in w_current
(something like:
GdkPixbuf *get_pixbuf_from_toplevel(TOPLEVEL *w_current) )...
Maybe I will be luckier any other day....
Cheers,
Carlos
