Canvas tools restructure

[Jacob-Griffin]

Re-lay out the canvas tools so that they're easier to use/less likely to mess up. Notably, there's too many buttons so some people fail to notice undo/redo. Also, the clear canvas buttons are one-click.

I made a rudimentary layout that should accomplish the task of condensing buttons (Line widths and clear buttons can be reduced), and adding a de-facto clear confirmation. (sorry dark mode users, sorry me)

The part of the design I'm not as confident on is the line width selector. Doing it this way adds a click for a pretty common scenario. However, not doing it this way means we add either

• 3 extra similar-looking buttons, which isn't necessarily a bad thing, but a bit weird.
• or an intrinsically horizontal control to the top-level layout.

Neither is that great, since more buttons is not very tidy, and a horizontal control means that it'll be harder to incorporate into a side-by-side single layout. Perhaps just having more explicitly styled groupings for the buttons?

Putting this in the ice box as the current structure works fine with the current layout

Given different things around this idea changing entirely, I would have to re-lay out this idea again. With the general understanding of the current layout being better too, I'll just close this. If we have a specific need to redesign the tools again, I'll make a new issue for that specific need. Closing.
