A prerequisite to porting a Sugar process, component or activity is to remove all its usage of hippocanvas. This library is unmaintained, would be painful to port to GTK3, and can be done better with standard GTK+ code at the Python level. Most users of HippoCanvas can switch to custom GtkContainer widgets.

One complication is that hippo usage is not limited to Sugar's core; some activities use hippo, or they pull on sugar-toolkit classes which are implemented with hippo. These are: Chat (<em>please list others here</em>).
