Alpha masking didn't correctly cut off the mask on some sides, if the mask was based on an icon rather than a render source.

Descriptive Problem Summary:
masking is ignored on the left side of an image

Numbered Steps to Reproduce Problem:
test case sent via pager
I'm trying to make head or tails of your test case here but I'm honestly not sure that you're not doing something wrong with the way the icons are setup. It's very hard for me to figure out which parts of the bar are which, and they're all positioned very oddly. The whole setup isn't really conducive to a good test case (particularly since the testBar verb isn't repeatable) and I'm highly inclined to think there's no bug at all.

I mean the pixel offsets here are truly weird. You've got one thing offset 199 pixels to the right, then a mask offset 198 to the left. What's going on with this?

Is there a way you can simplify the test case at all? Because I have a hunch that un-kinking all the pixel offset junk is gonna solve the entire problem.
