Allows the opacity of a raster to be varied e.g. on different
pages of an atlas, depending on the visibility of another layer,
by temporal variables, etc...
a few select dialogs
If the user has gone to the trouble of picking a CRS from the dialog,
it should ALWAYS be pushed to the list of recently used CRS, regardless
of whether they've done it from project properties, layer properties,
some processing algorithm, etc...
* Load the default relation editor if the relation editor type setting is missing
* Add setDefaultWidgetType and defaultWidgetType to the relation editor registry
* Use the new defaultWidgetType() when relation editor type setting is missing
keyword in Python, so this value was previously inaccessible to PyQGIS
scripts
Also change all references to Qgis::MessageLevel values to their
fully qualified names, to ease a future transition to an enum
class (when sip bugs are fixed)

which are subrenderers for other renderers
Symbol layers have no effect in this situation (e.g. when a categorized
renderer is used as a subrenderer for point displacement renderer), so
don't show the option in the GUI
Instead of directly changing the renderer in place in the symbol levels
widget, we delegate responsibility for handling the changes to symbol
levels to the parent QgsRendererWidget subclass. This allows us to
implement different logic in the various subclasses which correctly
handle how that particular widget subclass should update any internal
symbol references and ultimately update the renderer.
Fixes instability and crashes after editing symbol levels.
Fixes#42671
QgsMapCanvas::zoomToFullExtent
In 3.18 these methods changed their meaning from the "full extent
of all layers visible in the canvas" to "the full extent of the
associated project".
These are actually two different, equally valid use cases, so
disambiguate by adding new explicit methods projectExtent()
and zoomToProjectExtent(), and revert fullExtent() and
zoomToFullExtent() to their pre-3.18 behavior.
Fixes#43303
- Add enums to qgis.h instead of qgscoreenums, so that they belong to
a Qgis namespace
- Split up the various symbol headers into multiple files so that we
can fine-tune their inclusion and forward declare more readily, speeding
up recompilation
- Move QgsSymbol enums to qgis
