Moots: anti-click toggle buttons on the panel

[cosinekitty]

Right now, the only way to toggle the anti-click filter on one of the 5 control units in Moots is to right-click and select the option from the menu. I'm considering putting 5 small buttons on the panel that allow toggling anti-click, and using light/color to indicate their current state. I believe this will be a better user experience.

As of 36d1e75 Moots now has a menu item for the anti-click option on each of the 5 controller buttons. I'm also considering some kind of different appearance on the button to immediately indicate whether each of the controllers has anti-click enabled. I know color changes are problematic because a lot of people have color perception deficiencies. So I'm thinking about a little symbol of some kind on top of the button light. Any ideas (especially if they are easy to draw using C++ code)?

Here is what I ended up drawing on buttons that have anti-click enabled:
