s/when checked/when focused/

I haven't design the new checkboxes yet, I'll let you know.

Here's what I specced out, similarly to how I specced the buttons states.
You can also find the .svg for prog rendering attached.I also included the a selected radio and checkbox in .svg so you can grab the stroke spec.

.svg are 2x based, no need for 1x. Simply scale.

are there ripples? A hover state? (including on text next to the radio/checkbox)

So here's the best I can give you right now. Basically take the single tap ripple from core UI and apply it to the on-release state with a fade-in of the final state. Similar to the MDlite implementation you can find here: https://getmdl.io/components/index.html#toggles-section

question for sgabriel - I assume, based on the on-release spec, that we don't want to show the focus state (or invisibly take focus) when the user clicks a checkbox or radio button. Is this assumption correct? If so this will be a behavioral change.

Add ripples to md checkboxes/radio buttons

Not entirely sure this is what Sebastien had in mind, but it seems
like a reasonable starting point. Will ping him to test it out after
landing.
