 In current implementation of Canvas.drawExternalGraphic I found two
 problems:

 1) if using a (point) style with an external graphic, and NOT defining a
 pointRadius AND (graphicWidth OR graphicHeight), NO graphic was draws
 (there seems to be no default size for a graphic

 2) when using an external graphic and using the style properties
 graphicXOffset and graphicYOffset the offset was too big (eg using a
 marker graphic 24 pixels hight with a pointer to the bottom of the
 graphic, you had to give an y-offset of 24 to have the pointer point to
 the real point ...).

 I will attach a patch for both problems
