Correct reset the rendering context

[annevk]

6efd0e6 addressed #5771 incorrectly. The current default path should not be part of the drawing state, but should be cleared when resetting the rendering context.

(Also remove some older ideas from the source.)

Closes #5618 and fixes #5771.

Thanks, looks good to me, but I'm not well versed in editorial reviews.

LGTM. Of course it'd be better if this took explicit arguments and didn't say things like "canvas" and "context", but that can be future work.

@mysteryDate FYI (I thought you were already on the canvas team, just added you).

Thanks for clearing this up @annevk!
