Add an option to support grid line width updates

[Brian_McLeer]

Allow users to update line widths of grids to Grid Controls. Sometimes grid lines can be hard to see against aerial imagery.

Hi @Brian_McLeer, thanks for posting your idea here. Do the color and theme properties work for your use case? If not, could you explain how a width property would work better?

Hello @Noah-Sager and @bbollin, thank you for the quick response. Updating colors/theme can work in some cases. However in the image below when you have varying symbology on top of a raster basemap, the thinner lines can become muted even though the color is a bright orange. Allowing users to adjust overall thickness of gridlines would allow more contrast against content with high degrees of color. I would like to point the larger gridlines are not hard to see, but the smaller sized grids can be hard to see.
