9fc11d93c7 Add a trigger3DUpdate method to QgsMapLayer so that an explicit update of the layer in 3d maps can be requested

1963ef9784 [pointclouds] Add an elevation tab in layer properties, and allow 
users to set a manual offset to apply to point cloud z values

This allows for adjustment of the elevation of point clouds, eg so that:
1. They match nicely with point clouds from other datasources
2. Users can use point clouds from sources with arbitrary z values,
eg. a point cloud made by opendronemap without any actual reference
z values available

6ae7a17bf0 [API] Add an adapter class QgsBatchGeocodeAlgorithm which creates 
a batch geocoding algorithm from a QgsGeocoderInterface

Example usage:

  # create a class which implements the QgsGeocoderInterface interface:
  class MyGeocoder(QgsGeocoderInterface):

     def geocodeString(self, string, context, feedback):
        # calculate and return results...

  my_geocoder = MyGeocoder()

  # create an algorithm which allows for batch geocoding operations using the custom geocoder interface
  # and implement the few required pure virtual methods
  class MyGeocoderAlgorithm(QgsBatchGeocodeAlgorithm):

      def __init__(self):
          super().__init__(my_geocoder)

      def displayName(self):
          return "My Geocoder"

      def name(self):
          return "my_geocoder_alg"

      def createInstance(self):
          return MyGeocoderAlgorithm()

      # optionally, the group(), groupId(), tags(), shortHelpString() and other metadata style methods can be overridden and customized:
      def tags(self):
          return 'geocode,my service,batch'

0ab761c210 Add proper method to determine whether a symbol uses map unit sizes, 
and use this to determine whether a legend item needs updating
as a result of a map change

This results in a HUGE speed up when loading large projects where
symbols don't use Millimeter based sizes, as the previous code
assumed only that any non-millimeter size was a map unit based size.

39307900c6 When a point cloud is first added to a project, default to setting 
a 3d renderer on it to match its 2d renderer

da51a5a8d0 It's FAR too expensive to construct a QgsSettings object for every symbol node, especially for complex 
projects. So only read the valid size ranges once, and store them for subsequent use

4d9bc5bac3 Move responsibility for determining whether a map renderer job requires 
flattening onto a temporary image to the QgsMapLayerRenderer subclasses

This avoids the generic QgsMapRendererJob class from having hardcoded
layer type dependent behavior, and instead moves that layer-type specific
logic to the subclasses designed for that particular layer
