This release includes the usual set of bugfixes. New features are mainly centered around testing the library - there's a new "tests" folder which will grow into a comprehensive set of test harnesses for every UI gadget. The two existing tests have already highlighted a number of bugs in the tested gadgets, all of which have been fixed in this release.

Additionally, this release adds the ability for Woopsi applications to load and save 24-bit BMP files.
