This is now in compliance with the spec, using a single color with
opacity to render open/hovered/active GridItems and InfoPanels. We also
properly show background on open GridItems.
This patch makes immediate use of useTransientState() to fire a
temporary state transition to show success/failure of copy action.
Note: we should handle error states using other icon.
This patch extracts InfoPanel from IconGridItem, adds style tweaks to
match the spec, and in general reduces prop-drilling by tapping into
recoil state for most config, and making use of IconContext to style
member icons where appropriate :)
This patch adds throttling to events emitted by the native color-picker,
preventing noticeable lag caused by rapid state updates. It is currently
throttled to one event per 100ms, but we may want to play with this
value in the future! For not it feels smooth.
