#3151: canvas vector rendering problems using stylemaps

-----------------------------+----------------------------------------------
Rendering of vector features on canvas has some hickups.
See attached zip with some testcode: a simple KML with vector points, a
html to be used to switch between default renderer and canvas renderer and
a patched OpenLayers.js (to be able to better select on point features,
see #2839).
Looking at that test I see two issues:
1) There is no shadow for the markers visible (changing the renderer back
to default shows them).
Loading the vectorpoinst and using 'styleMap2' (with external graphics) =
actually http://openlayers.org/dev/examples/marker-shadow.html on canvas.
On Android you are stuck with canvas, so no shadows there)
2) using a stylemap with both a default and select class, sometimes BOTH
styles are painted over each other when you select a feature. Note:
sometimes painting is ok, sometimes it is not:
Loading the vectorpoints and using styleMap 'styleMap' in the
canvasbug.html and selecting the markers, you sometimes see them BOTH
painted.
