Hi Peter,
Yes there is. I'm using it to keep my image handle count down to a
minimum (I have viewer who show thounds of images). You need to use my
header_footer branch and there you'll find a class named
GridVisibleRangeSupport? It will inform you whenever the visible range
of cell has been changed.
I'm going to present those feature at EclipseCon in a short talk about
Nebula-Grid [1].
