This script searches for control points that are overlapping nodes and marks them with an annotation circle, setting also glyph's color to red.
How to use: select the glyphs and run the script. It works for one master at a time.
A much better tool for this is RedArrows by Jens Kutilek but it only works on Glpyhs 2.
