Hi Developers,

I noticed that the Air theme's graphic for the active task (on the task manager) was a pixmap, whereas the other button states were true SVG vector shapes.  As a result, the active task (appears as depressed button) didn't perfectly match the other button states, and there were alignment issues, such as the infamous 1px gap at the right edge of the active task button.

So, I recreated the active task button using vector shapes instead, and have attached the file here (./widgets/tasks.svgz).  This is based on the air theme version included with KDE 4.8.0.  FYI, after replacing the tasks.svgz file, you might not able to see the change in the air theme until after deleting the plasma theme cache file in ~/.kde/cache-hostname/.

I've also included this fix in the Frosty Air Theme on kde-look.org if you want to give it a test.  You may also want to consider the changes made to the Frosty Air theme for inclusion in the default air theme, since they improve text readability when the desktop effect "blur" is active (see KDE bug #278861).
