George Peter Staplin 2006.07.11 : As the Tcl/Tk core team is taking their time with Tk 8.5, I've been working on my own Tk9 for a few months. It implements a window system using Tcl, and some C extensions from megapkg (megaimage, megaimagetk, structure). It has full support for alpha transparency in any widget. You can rotate windows, and every color in Tk9 consists of [list R G B A].
Features so far include (from megaimage):

I have a working prototype of freetypeext.so:
Sample code that generated that is available here:

I plan to add kerning support, so that the text has better spacing between chars. Also see the text_playground.tcl file for further features I want to add that will be required for things like entry and text widgets.
I've started on my second prototype of a grid manager in Tcl. It now has -columnspan, -rowspan, and -sticky.

A little work everyday adds up to a lot.
At the moment it uses megaimagetk's megaimage.frame (in the demo) for fast shared memory image display. Future performance will be even better.
I have a demo/prototype that you can drag around the windows in, and watch as the alpha transparency works flawlessly with the windows.
Here's an example of the Tk9 demo (prototype WIP):

I'm open to new developers helping. Are any of you interested in a mailing list?
