Note that this is a resource-intensive filter. Memoization is strongly advised!
Known issue: Filter memoization will, sometimes, kill Safari-based browsers for as-yet-unknown reasons - see demo Filters-001 for details. For now, if Scrawl-canvas detects that the user is viewing the canvas in a Safari-based browser, it will ignore requests to memoize filters.
