+ <p>This example shows drawing simple vector features -- point, line, polygon
+ in different styles, created 'manually', by constructing the entire style
+ object, via 'copy', extending the default style object, and by
+ inheriting the default style from the layer.</p>
+ <p>It also shows how to use external graphic files for point features
+ and how to set their size: If either graphicWidth or graphicHeight is set,
+ the aspect ratio of the image will be respected. If both graphicWidth and
+ graphicHeight are set, it will be ignored. Alternatively, if graphicWidth
+ and graphicHeight are omitted, pointRadius will be used to set the size
+ of the image, which will then be twice the value of pointRadius with the
+ original aspect ratio.</p>
