Hi Anand!

Very impressive functionality you are working on!  I have a couple of
questions, both rather in the same vein -- potential improvements in
the form of contributions from others to this work.

1. I see that you are working from within a modified version of svg.el
(file seems to have the boiler-plan header comments saying it is a GNU
source, etc.).   Assuming I haven't misunderstood, would you be
interested in receiving back a new version of your work that separates
things into a stand-alone package?

2. Similarly, at last year's Emacsconf I shared a demo of
dm-sketch[1].  This is part of dungeon-mode[2] an Emacs-based RPG
engine this is my work-in-progress project for several decades. Sketch
for Dungeon is rather different from what (I believe) you have created
(so far).  Key examples:

(a) we use a "snap-to-grid" approach, and
(b) recursive tile-sets for placement ("Stamp tool") of complex shapes, and
(c) all "data" (SVG elements and SVG Path fragments, etc. composing
the tiles) are intended to be stored within org-mode tables.

These support key usability and accessibility goals of our project
which you can read about at the project link (#2, below).

I would, at least in potential, be interested in reworking dm-sketch
(and thus, dm-draw and dm-table which provides the key "primitives")
to be dependant on your work, potentially pushing some of the
functionality I need for (e.g.) tile-placement up toward your library.
  This assumes you are planning, as I assume in the first question, to
(eventually) make your package separate from the core svg.el

Would you be interested in seeing (for example) tile-set and
data-via-org-tables capabilities merged into what you are working on?

Thanks again for all your work in this area!
