Allow plugins to use alternative map projections
QtLocation mapping has always been geared around the WebMercator
projection. Some mapping SDKs support additional projections, such
as General Perspective (often called globe view or globe rendering).
The goal of this patch is to allow a plugin to provide such a view,
disabling WebMercator specific features, and redirecting API calls
to plugin-specific implementations.
In particular, this patch disables the rendering of Map Items
(QDeclarativeGeoMapItemBase and sons) for projections different from
WebMercator, with the exception of MapQuickItems.
MapQuickItems, in turn, lose the ability to draw "on the map", when
the projection is different from WebMercator. However, they can still
be used to add geolocated popups, buttons and other UI elements.
fitViewportToMapItems is also disabled, for both it can't be computed
and there wouldn't be any item to fit (with the exception of
mapquickitems)
