Drawing Simple Vector Features Example

Shows the use of the shows drawing simple vector features, in different styles.

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.

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.
