Hi guys,

I've noticed a big slowdown moving / deleting large quantities of
objects on a board with polygon planes.

What is strange, is that after deleting the planes, moving / deleting
the objects is still really slow - as if PCB is still computing the
polygons.

If you save the page after deleting the polygon planes, revert the page,
then moving / deleting objects is fast.

The effect is greatly amplified by my no-holes polygon caching code
(unfortunately), but it still appears to be present in CVS head. Any
ideas.. the polygon code scares me.

Best wishes,
