[OpenLayers-Dev] Patrch for getting vector drawing working over the 180 line going.

[Phil Scadden]

Worked part of today on the renderer. It seems to me that:

             var IDL = (this.extent.right > this.map.maxExtent.right);
is a very simple indicator of whether there is an IDL problem to deal with.
this.extent extends the projection coordinates over the 180 line rather 
than going to negative numbers.

Changing feature.geometry in renderer works pretty well. Only zoombox 
continues to do the wrong thing because the pixel to latlon creates 
negative numbers. Easily fixed. However, this still modifies the values 
of the feature.geometry rather than a clone because various other parts 
of the system (the handlers) independently modify the geometry so 
modifying a clone doesnt work.(rubberbanding stops working). I have 
little idea what effect that would have on other parts of openlayers. 
The critical thing will be for a polygon created for the purposes of 
selecting features through WFS but havent tested this yet. Geoserver 
handling of the 180 line is in a version that is giving us a problem 
with arcsde.

Will do more work on this tomorrow hopefully.

geodesic true fixes the distance calculation for measure control but 
area isnt working. I have yet to investigate why.
