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.

Called after the layer has been rendered for a particular feature.
This is always preceded by a call to startFeatureRender() just before the feature will be rendered.
The default implementation does nothing.

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.

Renders the symbol layer as an image that can be used as a seamless pattern fill for polygons, this method is used by SLD export to generate image tiles for ExternalGraphic polygon fills.
The default implementation returns a null image.
