Comment:
I need a way of interrogating features drawn onto a canvas. I would like to
use a canvas to represent layers/groups of features...which i control
wholistically as well as interrogate individually. Think of a map for
example....it has layers...where each layer has shapes. I could write a
logical model to store this information...but i can imagine that this is
something people will need in the future. The ability to select features by
criteria would be very helpful too....such as select features that intersect
or union feature X....or select all polygons within coordinates X or with a
name like Y. Thanks
