Comment 97 for bug 195929

So the style propery would mean "I can manage if you don't draw the background" and the widget data would mean "I won't paint the background if you can manage it". So Gecko asks for a transparent bg, and the theme tells it can handle that, for the naming I proposed it's the other way around. Either way suits me.

But I'm not really sure that the names are self-explanatory enough. Perhaps a "can-handle-transparent-background" ? The good thing is that naming doesn't affect the logic of the patch.

I'll take the bug, and write a patch along the lines of comment #41, modulo the naming which I will take from comment #42.

If that doesn't suit you, speak or be silent forever :)
