Scalar Bar Styling

Adds a border around the color bar and swatches. This creates a visual differentiation between the scalar bar and any grids of similar colors the scalar bar may be overlapping.

Adds a background to annotation text. This allows for partially transparent backgrounds to be applied to the text to increase contrast and text readability.

Adds leaders to text labels to better connect the label with a specific point on the scalar bar. A similar visual effect to how leaders are used for annotations.

Minor corrections to sizing and positioning to improve spacing between the scalar bar, swatches, and the border if not all swatches are enabled.
