Daniel M. Duley 7ba2cf2d87 Big ole speed improvement :)
First off, Rikkus was right about double buffering. I really didn't think this
was needed and tried everything to get rid of the flicker but it didn't happen
until I double buffered the title. I was able to optimize this quite a bit
(only recalc on resize, only buffer the active title/color scheme, etc...).

In the meantime, I got rid of a lot of non-optimal painting and now use
NoBackground for the widget. The latter was a obvious move as it avoids a whole
clearing of the widget :P This resulted in a big speed improvement, which helps
offset the time taken in buffering ;-)
