The whole point of a net-friendly window decoration is to not transfer
bitmaps, but simple fillRect/drawRect calls. As such, if it uses
gradients at all, it should not cache them.
If QPixmap is not entirely stupid, the pixmap is stored on the server,
yesno?
Thus you get no overhead.
QGradient however (still?, i think so) internally swaps to the raster
engine (because some drivers still *STILL* cannot XRenderCreate*Gradient)
ie. paints into an image and XPutImage's that to the server :-(
