Direct use of SVG Tiler in LaTeX

[edemaine]

Can we execute svgtiler directly from within LaTeX using --shell-escape, similar to svg.sty? Similar to #70, if we write an actual .asc file, we can detect if it's changed and only run SVG Tiler if so.

Alternatively/in addition, we could imagine a TikZ Tiler that runs entirely in LaTeX, and instantiates TikZ graphics according to ASCII art that's in the .tex file. There are even some attempts at converting SVG to Tikz: 1, 2, 3

Or a pure LaTeX implementation could use external graphics via \includegraphics, but re-use tiles via \setbox and \copy.
