This PR adds support for borders for scatter layers. Via the layer state, one can adjust whether to show borders, what border color to use, and what the border size should be.
In order to keep things from becoming too complicated, this doesn't allow using a colormap for the borders. However, there might be a case where a user wants to display unfilled circles with the layer colormapping for the borders. In order to allow this, this adds a
border_color_match_layer
flag in the layer state - when this is set to true, the border color is ignored and the layer coloring (fixed or colormap) is used instead.
