Verify anti alias text is working with semi transparent bg #10

The Speech Bubble module had this workaround for anti aliased strings that were draw in semi transparent backgrounds

In this module we render all the text and later draw it on top of the 9 piece textbox in the background - which should blend and not blit it.

Need to check if this works for the case where the font has anti alias and the background is semi transparent or we need some workaround. One possible source of issue would be with outlines.

But it's possible that the way we work things is alright too.
