Returns the estimated maximum distance which the layer style will bleed outside the drawn shape when drawn in the specified /a context.
For example, polygons drawn with an stroke will draw half the width of the stroke outside of the polygon. This amount is estimated, since it may be affected by data defined symbology rules.

Called before a set of rendering operations commences on the supplied render context.
This is always followed by a call to stopRender() after all rendering operations have been completed.
Subclasses can use this method to prepare for a set of rendering operations, e.g. by pre-evaluating paths or images to render, and performing other one-time optimisations.

Called after a set of rendering operations has finished on the supplied render context.
This is always preceded by a call to startRender() before all rendering operations are commenced.
Subclasses can use this method to cleanup after a set of rendering operations.
