imageobj saveimage method to take mapobject as argument.

[assefa]

Original message from Don Drake <dondrake@gmail.com>

I was wondering if there are any plans to update the PHP/Mapscript
libraries to get them more in sync with the Perl/Python versions.

I was trying to generate GeoTiffs with PHP/Mapscript and ran into some
troubles.  It would generate the .tiff file just fine, but there was
no geo-information embedded when inspecting with gdalinfo.

I tracked the problem down to the imageObj not taking a map reference
as a parameter when saving.  The Perl module does, and uses the
projection information of the map as a data source for the GeoTifff's
reference points and datum.

I was able to convert my PHP code to Perl/Mapscript to get this to
work, but would really like a single-code base (language) for my
project.

function saveimage can now take a map object as a second non manadtory argument.

Ex :  $img->saveImage("c:/msapps/gmap/htdocs/ttt2.tif", $oMap);
