This commit makes composer automatically georeference outputs
(where output format makes this possible, eg TIF and PDF).
The existing option to create a world file has been separated
from the map selection for georeferencing. The new behaviour
is to always georeference outputs, and only create the
separate world file if that option is checked.
This adds a new option in composer map properties:
"Follow visibility preset" with a combo box to choose the active preset.
This is an alternative to "lock layers" (and "lock layer styles") functionality
which would just copy preset's configuration, while the new option links to preset.
The difference is that when a preset is updated, composer map will automatically
pick the new configuration when following the preset, while there is no update
if "lock layers" (and "lock layer styles") option is used.
and new widget QgsComposerItemComboBox for showing matching composer
items.
Swap existing comboboxes to use the new widget, which removes a lot
of fragile code designed to allow selection of items. Additionally
the combobox now show the correct item id rather than always showing
"Map 0/1/..."
This makes it possible to change SVG fill/outline color and outline
width when using parameterised SVG files such as those included
with QGIS (fix#10542)
This check tests that if a function has been declared deprecated
with either Q_DECL_DEPRECATED or has a @deprecated Doxygen note
then it MUST have both the Q_DECL_DEPRECATD and @deprecated note.
It's important that both are used, as Q_DECL_DEPRECATED allows
throwing a warning if that method is used in code, while the
@deprecated doxygen note gives an indication to devs/PyQGIS users
of why it's deprecated and what should be used instead.
Ideally we'd also test for SIP /Deprecated/ tags, but I can't
find any reliable way to do this.
This introduces two new options to filter legend elements:
- filter by expression: a boolean expression can be set. Only symbols of
features that make the expression evaluated to true will be kept in the legend
- filter by polygon: only symbols of features that are inside the given
polygon will be part of the legend.
The polygon filtering is used in particular for a new option in the
composer legend that allows to filter out anything that is not included
in the current atlas polygon.
Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!
If selected, then the images output by composer will include only
the area of the composition with content. There's also an option
for margins to add around the item bounds if required.
If the composition includes a single page, then the output will
be sized to include EVERYTHING on the composition. If it's a
multi-page composition, then each page will be cropped to only
include the area of that page with items.
A new image export options dialog has been added to facilitate
this, which also includes handy shortcuts for overriding the
print resolution or exported image dimensions.

Allows composer map grid annotations in custom formats which are
evaluated using QgsExpressions. Made possible through the use
of Expression Contexts(tm)!

This allows users to set differing colors for alternating rows and
columns, first/last row/column and header row. Fixes#5131.

Previously multi-line text would overflow onto neighbouring cells.
Now rows will be expanded to fit required height of text.
Fix#10273.

Adds new data defined control for the map layers to show in a
composer map. Expression result should be a | delimited list of
layer names which will be shown in the map.
