Inside richmarker:

Rickmarker extends from Google. Maps. overlayview

Richmarker. Prototype. onadd

VaR panes = This. getpanes (); // returns the panes in which this overlayview can be rendered. The panes are not initialized until onadd is called by the API.
Panes. overlaymousetarget. appendchild(); // This pane contains elements that receive Dom mouse events, such as the transparent targets for markers. it is above the floatshadow, so that markers in the shadow of the info window can be clickable. (PANE 5 ).

Richmarker. Prototype. Draw

VaR projection = This. getprojection (); // returns the mapcanvasprojection object associated with this overlayview. The projection is not initialized until onadd is called by the API.
VaR latlng = (this. Get ('position '));
VaR Pos = Projection. fromlatlngtodivpixel(Latlng); // computes the pixel coordinates of the given geographical location in the DOM element that holds the draggable map.
VaR offset = This. getoffset _();
This. markerwrapper _. Style ['top'] = (Pos. Y + offset. Height) + 'px ';
This. markerwrapper _. Style ['left'] = (Pos. x + offset. width) + 'px ';
