Do not support only Polygon in gmd:EX_BoundingPolygon

[fxp]

Some community profiles allows to use point or linestring in gmd:EX_BoundingPolygon element. Those type of geometry are not indexed or displayed for the time being.

Example:

<gmd:geographicElement>
<gmd:EX_BoundingPolygon>
	<!-- Example for geometry with multiple points: -->
	<gmd:polygon>

In the example, point and curve are not supported, multiSurface is.

• In view mode, add support to draw those types of features
• In edit mode, add support to create those types of features
• Indexing: Those type of element could not be added to an ESRI shapefile (ie. mix of geometry types) but could be handled with PostGIS spatial index.
