Description

Often when you threshold e.g. a distorted gradient or bevelled shapes (frames in particular) you wont have the same thickness due to the stretching/distortion of the original gradient source.

This small snippet shows how to make strokes/outlines with uniform thickness from distorted sources (It also shows how to render nice ellipses).

The upper part (red), shows the trivial simple approach that produces non uniform stroke. The lower part (green) shows the essentials of this snippet: uniform stroke.

LIMITATIONS: The approach can reduce fine details in more complex inputs. Due to the high pass step, sharp corners gets rounded, see variation 3 (this is what you see if you uncheck Ellipse/Rounded Rect). Also due to the high pass step, close feature strokes may "melt" together as seen in the last variation (relative to the thickness).
