Scrawl-canvas v8 - Filters test 024

Test purpose

• Create a test Picture entity
• Create a curveWeights filter and apply it to the test entity
• Update the weights array using a second canvas displaying a set of curve controls

Usually best to create the weights array using some sort of tool where the user can shape and manipulate the curve - and also curves for each individual channel - to get the output they require for a given image.

Touch test: should work as expected. Known issue: the pins are currently too small for effective UX on touch devices.
