Stroke weight inconsistency depending on angle

## General description
I have just now seen your YT video about the new version and wanted to check out graphite as I never used it before. I first decided to try making a shape with the pen tool when I noticed that axis-aligned edges seem to have a smaller stroke width compared to inclined ones.

## How to replicate
1) Open the current Graphite version in your browser (Zen 1.20b / Windows 11)
2) Draw a shape with the pen tool that consists of axis-aligned edges and inclined ones
3) Observe

## Visualization
This is a quick visualization I made in blender as well as the original "raw" screenshot:

Thanks for your work and I hope this helps :)

Reproduce the issue in Graphite using the pen tool with both axis-aligned and inclined edges, as described in the steps. Start by tracing the pen-tool stroke rendering path and compare the resulting widths for each edge orientation. Done means strokes render with consistent weight regardless of angle, with a regression check for both cases.
