gio: Properly animate elliptical material.IconButtons v1 PROPOSED

I can understand if this feature isn't accepted because it is rarely
needed, but I thought I'd propose it just in case. The IconButton
animation code currently assumes that the button is a circle, which
makes the animation for a click appear off-center or weirdly aligned.

[PATCH gio 1/2] widget/material: handle elliptical icon buttons Export this patch

From: Chris Waldon <christopher.waldon.dev@gmail.com>

This commit changes the ink-drawing code so that IconButtons that
are not perfectly circular will still ink fully. Previously, an
elliptical icon would only animate a circular sub-region.

[PATCH gio 2/2] example/kitchen: [drop this commit] Export this patch

From: Chris Waldon <christopher.waldon.dev@gmail.com>

This commit illustrates the new behavior by making the previously-
circular icon button in the kitchen into an ellipse. I think it's
kinda ugly, so I recommend that this commit only be used to test
the patch and then dropped. You can see the previous behavior
by applying this patch first.
