Hi
why does QGrahicsView framework uses floats for coordinates ?
is it just to have larger maximum value possible or some other reason?
and
is there a performance penalty because of that if my hardware doesn't
have a FPU?
I found my Qwidgets to be signifacntly faster than QGraphicsItems. which
is unexpected considering docs say that QGaphicsitems are lighter than
Qwidgets.
