%Docstring
Construct a point with the provided initial coordinate values.

If ``wkbType`` is set to `QgsWkbTypes.Point`, `QgsWkbTypes.PointZ`, `QgsWkbTypes.PointM` or `QgsWkbTypes.PointZM`
the type will be set accordingly. If it is left to the default `QgsWkbTypes.Unknown`, the type will be set
based on the following rules:
- If only x and y are specified, the type will be a 2D point.
- If any or both of the Z and M are specified, the appropriate type will be created.

inclination is 90. A 3D point is always returned if a 3D point is projected.
