Nyall Dawson 65490ab13e Move QgsProject map scales settings to a new class, QgsProjectViewSettings
attached to QgsProject

And deprecate old getters/setters

The goal here is to create a place for project view related settings (e.g.
map scales, default extent, possibly future things like a fixed project
maximum area of interest, etc). Currently these are all handled in an
ad-hoc way, e.g. sometimes in project custom keys, sometimes inside
xml saved and restored by map canvases. But both these approaches break
important use case for plugins, e.g. creating a project from scratch
which will zoom to a desired extent on load. That's totally impossible
in the current API, unless you resort to extremely fragile manual
xml crafting...

class QgsProject : QObject, QgsExpressionContextGenerator, QgsExpressionContextScopeGenerator, QgsProjectTranslator
{
%Docstring
Encapsulates a QGIS project, including sets of map layers and their styles,
layouts, annotations, canvases, etc.
QgsProject is available both as a singleton (QgsProject.instance()) and for use as
standalone objects. The QGIS project singleton always gives access to the canonical project reference
open within the main QGIS application.
.. note::
QgsProject has two general kinds of state to make persistent. (I.e., to read and
write.) First, QGIS proprietary information. Second plugin information.

Most of the time you want to use QgsProject.instance() instead as many components of QGIS work with the singleton.

Configures a set of map layers that are required in the project and therefore they should not get
removed from the project. The set of layers may be configured by users in project properties.
and it is mainly a hint for the user interface to protect users from removing layers that important
in the project. The removeMapLayer(), removeMapLayers() calls do not block removal of layers listed here.

Temporarily blocks QgsProject "dirtying" for the lifetime of the object.
QgsProjectDirtyBlocker supports "stacked" blocking, so two QgsProjectDirtyBlockers created

which set the project as clean are not blocked.
