[OpenLayers-Users] DrawFeature: box supported?

[Tim Schaub]

Hey-

Yeah, if you want to use the DrawFeature control then you should use one 
of the handlers that Chris mentions (point, path, poly, regular poly).

See the regular polygon example for an indication of how to draw regular 
polygons:
http://openlayers.org/dev/examples/regular-polygons.html

Well, you may say "I want non square rectangles."  The RegularPolygon 
handler is about regular polygons (equilateral and equiangular). 
Because of this, I use the mouse down as the center of the feature and 
let the user rotate the feature with mouse moves.

However, we could give the regular poly handler an "irregular" property. 
  If true, this would allow for irregular polygons (rectangles, 
non-equilateral triangles, ovals, whatever).  The behavior for 
rectanlges would be similar to the box handler - first click is one 
corner, mouse moves drag out the opposite corner.

While it's a bit weird to have an irregular flag on the regular polygon 
handler, I think this would result in the least amount of code duplication.

I'll take a look at this later if nobody else gets to it first.
