RMMapContents crash for latitude window > 90 degrees

[GoogleCodeExporter]

What steps will reproduce the problem?
Call -[RMMapContents zoomWithLatLngBoundsNorthEast:SouthWest:] with two
points more than 90 degrees of latitude apart, such as 80oN and 20oS

What is the expected output? What do you see instead?
It should zoom to the rect, but instead freezes in an infinite loop.

What version of the product are you using? On what operating system?
Revision 173 on iPhone OS 2.2.

Please provide any additional information below.
I am attaching a patch that fixes this crash.  The crash happens when the
code subtracts two points and converts the difference from mercator to XY.
 If the mercator contains a latitude with magnitude > 90 degrees,
[projection latLongToPoint:latLongBounds] returns nan.  My patch fixes this
by converting the two points separately and subtracting the resulting points.

Is this still open? Please test both bug and fix against the current codebase 
and then commit. Thanks!
