Title: Implement draw_markers in the cairo backend.

This commit increases the speed of marker drawing in the caior backend.
It directly uses cairo paths for this. If the marker is only stroked
(and not filled) then only one drawing operation is used. If it is
filled then each marker is filled and stroked separately.
