Comment 31 for bug 723167

Mh, I've tried to apply a similar workaround as the one proposed on the patch, but it's not something we can apply in the way it is since we can't just draw a full bg over all our text, for many reasons...
One is that the panel can also be semi-transparent, and this will break it.

So, the only acceptable thing is to draw the bg only under the text glyphs, so that this will affect only the semi-transparent parts of text. I got something working here, but still I've to clean up and figure out a weird behavior I've noticed when the text is cut with fade.
