 It would be nice to be able to have geometry validation methods.  For
 example, A LineString isn't valid if it has less than 2 Points, a Polygon
 less than 3 and so on.

 '''Where would it be useful ?'''

 For example, while drawing a new feature with the DrawFeature control you
 can have unfinished drawn features.  Lunching a print request to the
 MapFish print module with the current layers would result in an error
 because of the invalid geometries.

 '''Version'''

 In 2.10, it's less of a big deal since features added to the handler
 vector layer (with the DrawFeature control) only when the user begins to
 draw.

 In current trunk, as soon as you activate the same control and hover the
 map with the mouse, it begins drawing a feature, which can result in
 having the issue more often.
