%Docstring
Returns ``True`` if the symbol rendering can cause visible artifacts
across a single feature when the feature is rendered as a series of
adjacent map tiles each containing a portion of the feature's geometry.
Internally this calls
:py:func:`QgsSymbolLayer.canCauseArtifactsBetweenAdjacentTiles()` for

Renders a context using a particular symbol layer without passing in a
geometry. This is used as fallback, if the symbol being rendered is not
compatible with the specified layer. In such a case, this method can be
called and will call the layer's rendering method anyway but the
geometry passed to the layer will be empty. This is required for layers
that generate their own geometry from other information in the rendering
context.
Since QGIS 3.22, the optional ``geometryType``, ``points`` and ``rings``
arguments can specify the original geometry type, points and rings in
which are being rendered by the parent symbol.
