I want to be able to iterate (left to right, bottom to top) the bounding box of a specific path, (I am guessing) one that has been "saved" using spath3. Why? I want to use it to fill the path with a custom fill but do not want to iterate outside of the bounding box (yes, still using clip).
So I need access to the bounding box of an arbitrary path.
The closest thing I can see is: Tikz: Shading a path without any filling
