get line width

overridevirtual |
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.

Returns the units to use for sizes and widths within the symbol layer.
Individual symbol layer subclasses will interpret this in different ways, e.g., a marker symbol layer may use it to specify the units for the marker size, while a line symbol layer may use it to specify the units for the line width.
