Right now the approach does a few tricks.
The first is creating a queue of spots we can color. This means that when you start making lots of dots, instead of searches becoming way longer when it keeps guessing wrong, or having overlapping dots, it knows which spots are left.
The second is that the from and to canvases can be different. So from could be hidden and to visible, or vice-versa.
onto means that you can color a polygon and look for it. Here you'd want to
use the two-canvas trick.
getImageData is an expensive call, so you can also supply an
instance as the first argument to
fill instead of Context and it will skip
re-requesting image data.
