Map tool for identifying features in layers
after selecting a point, performs the identification:
- for raster layers shows value of underlying pixel
- for vector layers shows feature attributes within search radius
(allows editing values when vector layer is in editing mode)

Returns derived attributes map for a clicked point in map coordinates.
May be 2D or 3D point.

%Docstring
Overrides some map canvas properties inside the map tool for the
upcoming identify requests.
This is useful when the identification is triggered by some other piece
of GUI like a 3D map view and some properties like search radius need to
be adjusted so that identification returns correct results. Currently
only search radius may be overridden.
When the custom identification has finished,
:py:func:`~QgsMapToolIdentify.restoreCanvasPropertiesOverrides` should
be called to erase any overrides.

Clears canvas properties overrides previously set with
