built-in possibility to add hatching for certain paths or alternative?

[ghost]

dear kartography team,

thanks a lot for the effort you put in creating and maintaining the library!

i am wondering if there is a built-in feature to add hatching to certain paths of a world map (e.g. those path ids not containing any data points in a datset that is loaded on top of the map).

static, non interactive example: http://stackoverflow.com/questions/14573010/cross-hatching-in-maps-using-r

or is there an alternative way?

kind regards and many thanks in advance,
tom
