Zoom in and out of canvas

None of the other digital drawing tools were my jam, so I wrote my own.

There were some early tests using escobar5/raphael-pan-zoom which:

Works in a desktop context but, as written, don't update the position and offset of the raphael-sketchpad pen so paths don't appear where they should.
Seems to work correctly in a mobile context except that the entire HTML canvas, rather than just the SVG element, is zoomed in and out.

There are two things to figure out:

UI/UX for taking raphael.sketchpad out of editing mode and listening for pan/zoom events
Adjusting the offset (_offset) for the pen in raphael.sketchpad
