My vision is to implement as much of the jsom as possible on the gwt.
Basically first to implement the rendering, then the editing.

I am starting to get an idea of a svg renderer and using svg
stylesheets to select how to style to maps. also click handling can be
done via svg. But my vision is basically to create a set of patches
for jsom that will separate the core map storage, rendering and
navigation in a reusable java component and to move the platform
specific code to a gwt or swing/awt lib.

I think it should be possible to read local files if they are for
example selected in an upload bot or accessible via an http request
