Draft: #9745: brush reset icon size
depends on !1198 (closed)
The 'reset brush to default values' icon now responds to custom icon size changes. With these particular icons, they shouldn't get huge at large sizes, they are meant to be stacked in a column and be fairly discreet. This MR demonstrates putting a limit on the icon size. It's a bit messy, but shows how to jiggle the sizes.
With respect to the custom icon size slider: There is 16px for small, and 24px for medium and large, and 32px for huge. Which is saying, if you want huge, you get large, otherwise you can have medium or small.
