Raster/Fill Feature

[Henry George Skupniewicz]

I know that this may be a departure from the core functionality, but as I think it would be useful and is included in the Axidraw Inkscape extension I think it has merit.

Basic idea would be to include ways to "fill in" or raster over areas. (i.e. https://wiki.evilmadscientist.com/Creating_filled_regions)

I could see this plug into #69 perhaps.

It would be good to have basic (back and forth) as well as circular and spiral rastering (though to start off with using the inkscape extension as a bench mark would be more than enough)

It would be cool if there was an ability to plug in a custom rastering routine too (though I have no idea what the best way to accomplish this would be).

While cool, I think filling shapes is much too complicated for saxi. Filling is best done as a preprocessing step over which you'll have much better control than saxi could provide.
