Stroke weight inconsistency between Shape tools and pen/pencil/spline tool

1) When we draw something using a shape tool(shape/ellipse/rectangle/etc) and when we draw something using the pen/pencil/spline tool, in both cases the default stroke weight is 2 px (visible in the Properties panel). However, as clearly shown in the video, the stroke weight appears different.
2) The stroke weight change behaviour during transformation that was resolved by the PR (https://github.com/GraphiteEditor/Graphite/pull/3854
)? That fix only resolved the issue when the figure is drawn using a shape tool(shape/ellipse/rectangle/etc). When the shape is drawn using the pen/spline/pencil tool, the bug still persists, as visible in the above clip.

Both the above mentioned bugs will be more or less because of the same issue.

Reproduce the discrepancy using the linked clip, comparing shape-tool output with pen, pencil, and spline output at the same 2 px stroke weight. Review the changes in PR #3854 and trace the transformation behavior for the pen, pencil, and spline tools. Done means consistent visible stroke weight and consistent stroke scaling during transformation across these tools.
