Don't copy the Graphics2D when binding a new one. This brings the
implementation in line with the interface documentation (the old behavior would
clobber any content).

The copying behavior was introduced to avoid flickering when resizing. To avoid
this, the PaintManager now doesn't bind the new device until it's been painted
to. This gives flicker-free painting.

This fixes a bug in the paint manager example that made it not paint.

I'm sure this code works fine.  However, if this gets changed, the pdf code's
heavily modified version of paint_manager needs to change as well.  this code
isn't paged in, and I'm quite a bit overloaded right now. can we look at it
together sometime and figure out if the changes here are port-able to the pdf's
paint_manager (i.e. tomorrow)?
