In a theme I'm making, I want to have all dock icons fairly low toward the bottom of the screen to maximize the wallpaper space. To this end, I've tweaked LiveClock.plist "origin" values for both hour and minute hands.

It all seemed to work fine, until I realize that the hands are being clipped, and looks like this:

Note that the blue part is part of LiveClock.png, which looks like this on its own:

I added the blue area to demonstrate that the hands aren't simply being clipped by the image's border, as it should, but is being clipped within an area that's defined somewhere else.

Can anyone help me fix this problem?
