I suppose it would have to be at least "medium risk" due to the total
amount of change; try "diff -ru" on the 6.2.1/6.3 versions.

OTOH, it's now completely detached from the graphics libraries. It
uses lib/display, but only for the stuff in cnversions.c, which is
completely isolated from the rest of lib/{display,raster} (that file
could even be moved into libgis).

Also, it no longer depends upon lib/form; it has a private version of
the form code. As v.digit is already a C+Tcl/Tk hybrid, there was no
reason to use a seperate etc/form process.

IOW, backporting v.digit shouldn't require any library changes to be
backported; that would have made it "extreme risk".
