Returns the "representative" color of the symbol layer.
Depending on the symbol layer type, this will have different meaning. For instance, a line symbol layer will generally return the stroke color of the layer, while a fill symbol layer will return the "fill" color instead of stroke.
Some symbol layer types will return an invalid QColor if they have no representative color associated (e.g. raster image based symbol layers).

Sets the "representative" color for the symbol layer.
Depending on the symbol layer type, this will have different meaning. For instance, a line symbol layer will generally set the stroke color of the layer, while a fill symbol layer will set the "fill" color instead of stroke.

Sets 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.

Called before the layer will be rendered for a particular feature.
This is always followed by a call to stopFeatureRender() after the feature has been completely rendered (i.e. all parts have been rendered).
The default implementation does nothing.

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.
