Yes, and it sucks indeed (at least in my build). The tab-middle*.png
graphics with alpha-transparency used to make the tabs shine use CPU big
time to display on OS/2. I guess this forces us to fork browser.css,
too, for OS/2. I filed bug 354955 about it.

I just hope that this doesn't cause other theme designers to follow
this... I better crosspost this for a wider audience.
