Recently Used Screenlet

This screenlet gives you access to your Gnome recently used documents list. The user can set the number of items shown and has control over all fonts, colors and sizes. Users can also "pin" documents to the list by clicking on the pin icon (it doesn't really look like a pin) to the left of the document icon. Pinned documents will stay on the top of the list until they are unpinned.

This is my first screenlet and I still don't know Python! If anyone has any suggestions I'd be happy to entertain requests.

My current TODO list contains:
- ?? :)

NOTE: I'd like to thank co-author Risethagain who has contributed great code, bug fixes and design ideas that have helped make this screenlet totally rock!

* 0.1
- Initial version

* 0.2
- Fixed bug that sometimes highlighted the item under the mouse cursor even if user had hover turned off.
- Added icons (with option to enable/disable)
- Small performance tweak to prevent some wasteful redraws on start up
- Using callback to update list when recent docs change instead of just updating every 5 seconds

* 0.3
- Fixed large performance problem with icon drawing by caching GDKPixBuf 's for all icons in the list

* 0.4
--- Following changes by: Risethagain aka Matjaz Pecan ---
- Fixed font handling. Fonts set by the default themes now work properly. Also, user's font size choice is now respected.
- Added option to disable corner rounding (available to themes only)
- Longer filenames are truncated according to the width set in the properties dialog (shorten_name_gracefully) (IE: 123456789.tar.gz would become 123...89.tar.gz with a maximum size of 15 set)
--- Following changes by: Jason J. Herne ---
- Removed "num_chars_per_item" option as Matjaz's changes make it obsolete :)
- Removed slow theme as recent performance fixes make it pretty much pointless
- Themes no longer modify max_docs_shown and list_width settings, now we respect the
- user's settings when they switch themes

* 0.5
- We now set the window shape properly thereby avoiding a bug where overly transparent (or undrawn) areas of the screenlet do not detect mouse movement or mouse clicks

* 0.6
--- Following changes by: Risethagain aka Matjaz Pecan ---
- Fixed the problem with filenames that have more than one period in them and are not double extensions(like .tar.gz). Example: "01 - Preston, 11.06.1994 - Shakermaker.mp3" was being converted to "01 - Preston, 11.06.1994 - Shakermaker.m...994 - Shakermaker.m...".

* 0.7
- User can now pin documents onto the list which makes them permanent items that will always show up at the top of the list in alphabetical order. To pin or unpin a document simply click on the "pin" icon to the left of the document's icon.
- Created new theme: Sky Blue
- Fixed bug causing "Properties,About" dialog to be blank. Apparently you cannot use a '&' character in the authors field ;)
--- Following changes by: Risethagain aka Matjaz Pecan ---
- Wrote custom draw_triangle function to improve the triangle control used to expand/contract the documents list

* 0.8
- Fixed bug that caused screenlet to crash if an icon could not be loaded.
