The googlemaps plugin is about to support tile language
via the PluginParameter 'googlemaps.maps.language'.
To be able to pass the subsurface UI language (obtained
from the uiLanguage() helper) the Plugin has to be created
dynamically, only *after* the MapWidgetHelper is created.
MapWidgetHelper::pluginObject() now provides a QString which
contains the Plugin object and also include the uiLanguage
ISO value.
This string is used in mapwidget.qml as:
map.plugin = Qt.createQmlObject(pluginObject, rootItem)
This creates the Plugin object dynamically with the proper
UI language string, but also requires a couple of small changes:
- move the declaration of map.mapType after the
Qt.createQmlObject() call
- assign map.activeMapType after map.mapType has a value

The QML Map has a couple of methods - toCoordinate(someQPointF) and
fromCoordinate(someQGeoCoordinate). Ideally, if one passes a point to
toCoordinate() and then attempts to convert the resulted coordinates
back to the point, the same point in the Map view port with minimal error
should be retrieved. That's not always the case - e.g. near
47.400200 -123.142066, which means that the methods are not exactly
*reliable* and there might be Map class bugs at hand.
The new zoom-in and zoom-out improvements try to work around the above:
- for both centerOnRectangle() and centerOnCoordinate(), if no good
zoom-out level is found (newZoomOut), the zoom-out is set to the default
value of defaultZoomOut. In practice, this prevents the case where the map
does not zoom-out at all when going from one place to another
- centerOnRectangle() now uses rectangle diagonals to estimate a fit,
instead of checking if 2 points (top-left and bottom-right) are visible
in the viewport. The usage of fromCoordinate() was giving bad results
in this case and comparing distances (diagonals) is more reliable
but more expensive on the CPU.
Due to the inconsistencies of toCoordinate() and fromCoordinate()
the dynamic zoom-in and zoom-out are still not ideal, but the current
implementation is somewhat usable with decent accuracy.

MapWidgetContextMenu now has a new action (SELECT_VISIBLE_LOCATIONS),

First, this function calculates the zoom out effect until both the
current Map center and the target rectangle are visible - see the
"calculate zoom out" part.
Then it calculates a zoom level, so that the target rectangle
fits the viewport, but also so that the zoom is not too much (clamped).
see the "calculate zoom in" part.
NOTE: "centerStored" (the variable used to store the current map center)
is created using QtPositioning.coordinate(), because the code needs a new
object and not a reference of the map.center QGeoCoordinate object.

Add stopZoomAnimations(), which is really just a precaution
function to make sure we have stopped all animation of the
map before doing calculations! Since the animation *should*
be running in a separate thread, this would make sure the Map "center"
and "zoomLevel" properties do not change.
Add pointIsVisible(), which is a helper to determine
if a point created by map.fromCoordinate() method is inside
the viewport. fromCoordinate() has to be called without the
"false" (clip) flag for this to work.

MapWidgetHelper::centerOnDiveSite() now checks if more than
one dive sites are selected and finds the most top-left and
bottom-right ones in the coordinate system to form
a rectangle.
It also supports the special cases where a selected dive site
does not have coordinates or the case where only a single dive site
with GPS coordinates are selected.
TODO: implement mapwidget.qml::centerOnRectangle()
This QML function will receive a QGeoCoordinate based rectangle which

With the satellite map ([1]), the black tiles at relatively high
zoom levels over the Red Sea cannot be seen. Instead it shows white
tiles at the ultra-maximum zoom level at places.
As a side note, the "satellite" map does not have the country labels
which the "hybrid" map has.

This patch makes use of the geolocation plugin "googlemaps"
for Qt Location with source code from here:
https://github.com/vladest/googlemaps
The change from the ESRI plugin is that it requires new indexes
for the Hybrid ([3]) and Street ([0]) map types.
There are more zoom levels in this plugins, but our default zoom-in
settings seem to transition well to it.

The editing support is added via dragging. It is handled via the
MouseArea's drag.target of the MapQuickItem. The drag target changes
with the model selectedUuid.
"mapAnimationZoomIn" now also does an initial zoom-out before moving
to a new location.
centerOnCoordinate() now pefroms calculations to determine how much
the animation needs to zoom out. What it does is it reduces the Map
zoomLevel util both the current and the new target coordinates are visible.
It then restores the zoomLevel and performs animation based on newZoomOut.
animateMapZoomIn() is now obsolete.
The patch also includes the following smaller changes:
- remove the setSelectedUuid() call in deselectMapLocation()
This is now handled in C++
- sets "defaultZoomIn" to 12.0
- use ">=" when determining if a mapItem text should be visible

The MapItemView delegate now includes a white Text element.
It uses the MapLocation "name" property as text.
This text is only visible if the map zoom is above "textVisibleZoom".
For hundreds of dives, using the DropShadow effect for the text
makes it laggy. Instead, using a fake drop shadow (duplicate black
Text under the default text) makes it much better.

The signal emits a QList<int> filled with dive idexes from the
main backend dive table.
The MapWidgetHelper QML instance handles that in onSelectedDivesChanged().
This will only be needed for the mobile version, as the desktop version

The idea of this flag is to be able to only to emit the
selectedLocationChanged() signal when the user clicked on the map
(fromClick == true).
MapWidgetHelper::selectedLocationChanged() listens for this signal
and only then it will select nearby dives based on a "small-cicle".
If "fromClick" is false, it's the backend or the dive list that
updated the selection and MapWidgetHelper::selectedLocationChanged()
should no be called.

The actionSelected() signal is now dispatched when the user selects
an action from the menu (see the "actions" object). Then the declaration
of the MapWidgetContextMenu object in mapwidget.qml can catch that
signal in the onActionSelected() slot and obtain the action via
switch() branching.
The actions enumeration is kept in QML for now, with the idea that
specific C++ methods from the mapwidgethelper class will be called
directly (if marked as Q_INVOCABLE), instead of a generic
onMapAction(action) C++ method in the helper. But if the actions
are possible from QML (like copying to clipboard) and are also
small and non-expensive, it might be better to keep them
in mapwidget.qml.

Make the "enumeration" local to the Map object for now.
This will possibly break if another plugin is used in place of the
ESRI plugin, but it will simplify the map toggle button which is about
to be implemented next.
If support for multiple plugins is added on runtime a simple
helper function will be needed that will check the current plugin "name".
And return the appropriate supportedMapTypes[X] for e.g. STREET of that
plugin.

The animation sequence when deselecting a zoomed in map location, should
be:
- zoom out completely
- pan to center
To achieve that a new animation object is created - "mapAnimationZoomOut"
The previous zoom in animation is renamed to "mapAnimationZoomIn".
The map functions centerOnMapLocation() and deselectMapLocation()
now call the helper functions animateMapZoomIn() and animateMapZoomOut().

Instead of maintaining a seperate latitude/longitude values

MapItemView is the QML class that handles the "create map markers based
on a model". In this case the model is created as part of the
MapWidgetHelper, so here passing "mapHelper.model" to the "model"
property is enough.
The delegate receives coordinates from the model as "model.latitude",
"model.logitude" and converts them to QGeoCoordinate.
The "sourceItem" image for the delagete is just an image ATM and is
fetched from QRC.
