Perl typemaps for image->write & map->process

[lfilak@…]

SWIG typemaps required for the image->write, map->processTemplate,
map->processLegendTemplate, & map->processQueryTemplate to work in PerlMapScript.
A patch file, currently for 4.4.2, will be attached and then for 4.6.0-beta3 as
soon as available.

4.4.2 typemap patch

[sgillies@…]

I don't think there will be a 4.4.3 release, but I don't mind applying the patch.
For 4.6, we're getting away from imageObj::write() and recommending that modules
implement imageObj::getBytes() instead. It's less confusing. Only file-like
objects should be writing. The Python and Java mapscripts have getBytes for the
version 4.6. You could look at those for examples.

I will inform the developer of the name change. The 4.4.2 patch is only intended
as a sample until the 4.6 patch is available.

I think this method may be best left as 'write' as it is a file-like object.

[sgillies@…]

I think this is a difference in usage style between Java/Python and Perl. With 
Python it is more natural to do this

    print imageObj.getBytes()    # send image data to stdout

I looked again at the Perl ImageMagick API and that does indeed use something
more like

    imageObj->write(STDOUT);

It is fine with me if you want to implement only the write method for Perl. The
sooner you can patch against the 4.6 beta 3, the better because I am running out
of time to help with this before the conference.

Patch for 4.6.1 for image->write & map->processXtemplate

[sgillies@…]

reassigning. i'm pretty sure i committed this one.

[lfilak@…]

Same as before just not gzip'd

[lfilak@…]

Example of imageObj->write

[lfilak@…]

Example of mapObj->processXTemplate

[lfilak@…]

Mapfile for both examples.

[lfilak@…]

Template HTML for processLegend.

[lfilak@…]

Template HTML for processTemplate.

[lfilak@…]

A bad attempt to get processQuery to work.
