Returns the estimated maximum distance which the layer style will bleed outside the drawn shape.
Eg, polygons drawn with an outline will draw half the width of the outline outside of the polygon. This amount is estimated, since it may be affected by data defined symbology rules.

Returns the offset along the line for the marker placement.
For Interval placements, this is the distance between the start of the line and the first marker. For FirstVertex and LastVertex placements, this is the distance between the marker and the start of the line or the end of the line respectively. This setting has no effect for Vertex or CentralPoint placements.
