This adds settings to dot and square materials to add randomization to the size and color of dots. These settings control the Size, Strength, Rotation, Hue, Saturation and Value, of dots. There's also a setting to scale the noise along the stroke. The three settings for color randomization match the existing color randomization on brushes (except for the position jitter). Note: Position randomization is not implemented out, due to some technical limitations. Pull Request: https://projects.blender.org/blender/blender/pulls/155394
