Re: Please don't drop support for Curve

[Danielle Madeley <danielle madeley collabora co uk>]

Thanks to GObject-Introspection you could copy the code from GtkCurve
into a small C library that is bundled with your program and generate
gobject-introspection bindings for it to use with PyGObject.

This would also allow you to grow GtkCurve into something that meets
your needs.
