This ensures that we correctly apply filters to recent projections
too, eg so that a widget showing only vertical crs will ONLY show
recent VERTICAL crs, not every recent crs.
Cleanup QgsProjectionSelectionWidget to use proper models to
drive the combo box. This removes a bunch of very fragile
logic regarding showing and hiding entries on demand, as it
allows us to move all the filtering logic to a single place
in a QSortFilterProxyModel subclass.
This has a few side benefits:
- The combos now dynamically respond to changes like recent
CRS being used in other places in QGIS
- The widget correctly respects horizontal/vertical crs filters
for all entries, including recent crs
Sets whether changes to the active layer should be temporarily
blocked. Exposes a previously private optimisation for use
by plugins.
This is a low-level method, designed to avoid unnecessary work when adding lots
of layers at once. Clients which will be adding many layers may call blockActiveLayerChanges( TRUE ) upfront,
add all the layers, and then follow up with a call to blockActiveLayerChanges( FALSE ). This will defer emitting
the active layer changed signal until they've added all layers, and only emit the signal once for
the final layer added.
This adds a new line symbol type which renders lines using a
fill symbol. The interior of the line is drawn using any standard
QGIS fill symbol, allowing for lines filled with gradients, line
hatches, etc.

The symbol ownership of QgsSymbolSelectorWidget is very messy, and
we can't fix till 4.0. Workaround this by introducing a temporary
API to transfer symbol ownership to the widget.
This option (available from the new Settings - Options - Elevation tab)
allows users to set a specific color to use as the background color
for elevation profiles. This can make the chart more readable for
certain datasets, eg point clouds with RGB coloring, where the default
background color is too close to the point colors to be discernable.
This is an opt-in setting -- by default the profiles will continue
to display using the standard system background color.
