-    <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>

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