I have abjectly failed. Everything I tried increased resize time. xforms is averaging 1.5 seconds for first-time-resize. Qt is averaging 5.5. I can not bring this down.
4.5 seconds of this is time as a result of qfont_metrics::width() (checked using an empty ::width() function). Basically, our hands our tied by text.C's massive overuse of the metrics. This will have to stay, basically.
