[OpenLayers-Dev] Taking a look at ModifyFeature()

[Jeff Dege]

When ModifyFeature is active on a vector layer, when a feature is
selected, ModifyFeature breaks the feature down into its component
points and inserts them (and an equal number of virtual points) into the
layer.

If the layer has preFeatureInsert() and/or onFeatureInsert() methods
defined, these are called for the component points and virtual points
that ModifyFeature is inserting into the layer.  But generally speaking,
whatever logic the developer intended to be performed on the features
for that layer, is probably not wanted to be performed on the component
and virtual points that ModifyFeature is inserting.

Would it be reasonable for ModifyFeature to set some attribute on the
points that it is inserting that a developer could test in
preFeatureInsert()?  Or is there some other way of dealing with this
issue?
