New quark style

I made new quark graphics, like I promised last devlog. I’m not really sure if it fits the aesthetic I’m going for, but it’s something, and I tried to make it extensible so that I can experiment with more styles later.

I also added a dropdown menu in the setup flow so that you can select which style you want to use, though I might remove that in the future if I decide on one style to be the definitive one.

The new style is just patterns masked onto the same flat color circles as before. Each flavor has a different pattern:

• up: vertical lines
• down: horizontal lines
• charm: checkerboard
• strange: square grid with irregular shading
• top: light dot grid
• bottom: dark rhombus grid
• hadron: solid (unchanged)

I don’t know if this makes the quarks look nicer or not, but it definitely makes them more accessible. If the abbreviation text isn’t visible for whatever reason (e.g. because the chamber is in count layout mode), quark flavors used to be distinguished solely by color. But the new patterns make them distinguishable without color, which is important for colorblind accessibility.
