Update to 0.9.21:

Tux Paint 0.9.21 features nearly two dozen new Magic tools, as well
as updates to old favorites. Many of these were developed by six
students from around the globe during Google's 2008 Summer of Code
program, under the mentorship of Tux Paint developers.

Exciting new Magic tools include intelligent train tracks that
automatically connect when their paths cross, a realistic rainbow
tool, a fisheye lens effect, edge and silhouette tracing tools,
various string art effects, and a tool to fold the edges of your
drawing up from the corners. There is also a brush that paints with
'toothpaste', and others that paint with confetti, rain, snowballs,
and snowflakes! Additionally, many classic Magic tools (like Blur
and Tint) can now affect the entire drawing, instead of just a
selected area.

Coloring-book style Starter Images are now easier to make. Images
with transparency (alpha channel) are still supported, but
additionally, if no transparent layer is found, Tux Paint will
assume that white is the background color. This means you can now
draw or scan any simple black-and-white image and use it as a Tux
Paint Starter Image!

New in Tux Paint 0.9.21, the Text tool now supports bidirectional
languages like Hebrew and Arabic, thanks to the FriBidi library.
Tux Paint has also been translated to two new languages, Shuswap
and Songhay, and many other translations have been updated.

On Linux, environment variables (like "$HOME") may now be used when
setting directories for saving images or finding data files.

And of course, Tux Paint 0.9.21 incorporates a number of minor
improvements and bug fixes requested by the Tux Paint community.
For example, Tux Paint no longer drops out of fullscreen mode in
Windows if the [Windows] key is pressed (XP, 2000 and Vista only),
and it brings up an error window if it fails to print.
