 I've created a Spatial Index package/class that does helps out a lot
on a ShapePlugin layer.
It's loosly based on the Shape.SpatialIndex, with minor changes.
It's only a lineas search right now, but it makes it concidderably
qucker to redraw the screen.
I'll share it to be included if there is an intrest.


P.S. I also tried it with an R* tree, but the improvements were
marginal, and creation time was exponential.
