If the extension point refers to a panel mark, the parent of the new mark will be that panel. Otherwise, its parent will be the parent panel of the mark of the extension point.
The following example shows how to add an image to an axis tick:
function yAxisTick(){
return new pv.Image()
.url('res/images/arrowYy.png')
.lineWidth(0)
.height(7)
.width(5);
}

The possible values are: 'none', 'painted' and 'all'.
See the associated protovis documentation at http://mbostock.github.com/protovis/jsdoc/symbols/pv.Mark.html#events.
The default value, -1 has all bits with the value "1".
Only the bits for which #imask is "1" are considered.
Bits can be combined by using a "|" character, for example:
"Selectable|Hoverable"
