The rectangle/circle shape of Holders and Automation Buttons can have a background and/or border applied.
Label Text and Automation Button widgets can have fills applied to the text itself text and/or outlines.
Outlines trace the edge of the shape or text.
Size - The thickness of the outline.
Offset - The outward gap between the object and outline.
Up to 6 outlines can be added to a given shape or text. Outlines lower in the list are placed on top of those above, potentially covering up outlines above.
The color/contents of backgrounds and outlines is determined by a fill.
There are currently four fill types:
Solid Color - A single color covering the entire area.
Linear Gradient - A straight gradient from one edge to another.
Radial Gradient - A gradient starting from the center to the edges.
Conic Gradient - A gradient starting as a vertical line, spinning around the center 360 degrees. Ideal for Outlines that change color around.
An Angle can be specified on Linear Gradient and Conic Gradient, which is is used to rotate the gradient.
