I should have mentioned this the last time this came up: It is possible
to get a real python module for an import filter:

in 0.6, if you know the name of the fileformat as used by the filter:

from Sketch import plugins

module = plugins.find_export_plugin(name).load_module()

In 0.7 only the import changes:

import Sketch.Plugin.plugins

There doesn't seem to be a similar function for import filters, so you'd
have to search through the list plugins.import_plugins to find it. A
patch that an import filter equivalent for find_export_plugin would be
welcome, though.

A way for the user to enter parameters for the filters would indeed be
nice to have.

What native canvas? AFAIK, Gnome has a canvas, but not GTK.

Patches.
