[Mapserver-users] documentation bug (was Re: projecting a pointin PHP MapScript)

[Daniel Morissette]

FYI I have applied the 3.7 fix for this problem in the 3.6.5-dev version
in CVS.  You can get it using 'cvs update -r rel-3-6-0-beta1'.

With this fix, the project() methods return MS_SUCCESS/MS_FAILURE and
operate on the object itself, so they do not try to return a new object
instance.
