Diffusion controls
The Diffusion controls allow you to manage how and when the paint is diffused on the
canvas. You can specify that diffusion be precisely applied to ensure accurate paint
dispersion. You can also delay diffusion so the effect is applied only after you complete
a brushstroke. In addition, you can choose to suspend diffusion temporarily. This lets
you apply multiple brushstrokes to the canvas before applying the diffusion, to apply
the effect to all brushstrokes at once. You can also specify the number of flow steps to
be completed during animation. This controls the rate at which the visual flow of the
paint refreshes onscreen. For example, you can specify a lower number of steps for
smaller brushes and a higher number of steps for bigger brushes.
