This now follows the approach used for bearing formats, where a user
can defined a default coordinate format for newly created projects
in the Settings - Options - Map Tools section.
New projects will inherit that setting, but the format can then
be changed through the Project Properties - Coordinate Format button.
This ultimately exposes more control to users for how coordinates
are formatted for a project, eg allowing them to control whether
direction suffixes are shown, and whether leading or trailing zeros
should be included.
This class contains a variety of default setting values. These values are local, profile
specific settings which may have been configured or tweaked by the user (as opposed to
global, fixed default settings).
The values encapsulated here should be inherited when creating new objects such as new
QGIS projects.
Typically, the QgsSettings backend is used to store and retrieve these local settings.
The intention here is to provide stable, structured and easily discoverable
methods for setting and retrieve these settings, rather than forcing raw QSetting
handling.
