Improve the nodes' drop shadow by making it scale with the view and replace the loop for the alpha calculation with something more explicit. The amount of drop shadow softness was scaled with the zoom level and therefore had a fixed screen space size. DPI and UI scale weren't taken into account either. This patch fixes both issues by basing the shadow softness on the `widget_unit` that scales correctly in zoomable views and takes UI scale etc. into account.
