Bug 1803, Upcoming breaking changes for 4.10.0-beta1

[Tamas Szekeres]

Hi All,

According to the
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1803
and the agreement on the recent IRC meeting the following object
members will be marked as immutable on the SWIG interface:


  layerObj.metadata (hashTableObj)
  classObj.label  (labelObj)
  classObj.metadata  (hashTableObj)
  classObj.layer  (layerObj)		already marked as immutable in mapscript.txt
  fontSetObj.fonts  (hashTableObj)
  imageObj.format  (outputFormatObj)
  labelPathObj.path (lineObj)		missing documentation about
labelPathObj in mapscript.txt should we expose at all?
  legendObj.label  (labelObj)
  legendObj.map  (mapObj)
  mapObj.symbolset (symbolSetObj)
  mapObj.fontset  (fontSetObj)
  mapObj.labelcache  (labelCacheObj)
  mapObj.reference  (referenceMapObj)
  mapObj.scalebar  (scalebarObj)
  mapObj.legend  (legendObj)
  mapObj.querymap (queryMapObj)
  mapObj.web  (webObj)
  mapObj.configoptions  (hashTableObj)
  webObj.map  (mapObj)
  webObj.metadata  (hashTableObj)

Generally there is no need to create these objects externally since
they have been created internally.
External creation of these members are unsafe, instead folks should
work with the already created objects by reading the members mentioned
above.

If I get no objections till Aug 17 10:00 (Central European Time) i
will change map.h and mapscript.txt accordingly so as to get it for
4.10.0-beta1.

Regards,

Tamas
