This code in Cairo only, but if the Qt port is interested in this feature, I'm willing to write it using QPainter. The reason I did not use generic GraphicsContext APIs it that it would require some interaction with the FontCache and using the toy platform interface seems simpler all around.

I'm ok with the texture-mapper changes, though I'm not qualified to review the cairo-specific code :)
We'd love a QPainter implementation of this, though we'd have to do this in the LayerBackingStore code which is the proper place in WebKit2.

This would be more readable inside the function.

I'm just not sure about the border color, feels like you may want to have a border distinct from the background, but I guess it'll look readable like this anyway.

Hmm, I think it would be less readable with different implementations taking the whole function body. As it is now it's pretty obvious that each implementation has a completely different implementation.
