We relocated window measurment logic into a hook, useGridSpans(), which
tells us the appropriate number of columns for the IconGrid. This is
useful for rendering an InfoPanel in the right place! In future we
should look into a custom implementation using ResizeObserver and
polyfills, and that may be extensible for other use-cases.
When setTransientState() triggers a new timeout, we clear any pending
timeouts to prevent stale state from being applied if a superceding
value was set in the interim.
Maybe in future we should also allow users to cancel pending transitions
directly, by returning useTimeoutFn's cancel() function along with the
state and setter.
This utility hook provides access to a piece of state and a setter
function, which can be used to supply a temporary value and a duration
for which it is valid, before reverting to preceeding value. Following
the pattern:
const [value, setTransientValue] = useTransientValue<number>(42, 5000);
setTransientValue(69); // value === 69 for 5000ms, before returning to 42
We can easily fire and forget a temporary state transition.
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.
