Investigate fingerprinting potential of CanvasRenderingContext2D.filter
https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/filter got added in Firefox 35. We should investigate its fingerprinting potential. This can at least wait until we prepare an ESR 45 based release as this feature is still behind a preference in ESR 38 (canvas.filters.enabled
is set to false
)
