draw shape/arrow/nodes/paper symbols
This commit removes some more instances where changes in the
canvas affect compositions. Previously the symbols drawn
in shape/arrow/etc items were using the scale from the canvas.
This meant that the appearance of these items in composer
would change depending on canvas zoom if they used symbols
with map unit sizes.
Now they take their map scale from the composition's reference
map. While this has the nice side effect that now map units
can be used in the appearance of these items and they're
guaranteed to match up with the reference map item, the main
intention here is to remove more of the forced links between
compositions (core) and the main canvas (app).
This option will be used for more than just world file generation,
and instead will indicate which map should be considered the master
map for the composition from which any composer properties
calculating map units will derive the scale from.
This adds a new item_variables expression function when expressions
are used inside a composition context.
The function takes a single argument, the id for an item inside
the composition, and returns a map of variable name to value
for that item.
This allows you to do things like insert text in a label fetching
properties of another item in the composition, eg
Insert scale of map into a label:
map_get( item_variables( 'map'),'map_scale')
Insert x coordinate of map center into a label:
x(map_get( item_variables( 'map'),'map_extent_center'))
spell check will be done automatically in words by default (when some conditions are fulfilled)
possibility to avoid in words checking by adding :* at the end in spelling.dat
one can add #spellok at the end of a line of code to skip spell check on this line

The commit d44f1eba2fed18b3fef8d8865d79b3b6d8bc4d69 seems to break some WMS 1.3.0 client and WMS compliancy.
The commit d44f1eba2fed18b3fef8d8865d79b3b6d8bc4d69 has been written to fix an issue with QGIS WMS Client and to render image like other WMS Server.
This commit has been written to fix issue introduce by d44f1eba2fed18b3fef8d8865d79b3b6d8bc4d69.
It is based on MapServer code:
* https://github.com/mapserver/mapserver/blob/master/mapdraw.c#L115
* https://github.com/mapserver/mapserver/blob/master/HISTORY.TXT#L3768
And take account of axis invertion for output CRS.
