Graphics twitter, how do you handle clipping of child UI elements inside of another element that has arbitrary vector graphics? Rounded corners being an example that comes to mind. Stencil? Something else?

If the clip just needs to be a rectangle, as is most of the time, I just use scissor. But yeah, if you need something other than that, stencil is likely the best route? Sometimes you have no stencil bits though. I suppose you can also clip the geometry on the CPU too.
I’m still in the early stages, but cpu clipping is already what I’m doing for oriented shapes inside of oriented shapes. I don’t really want to tesselate a rounded corner though.

If you just need to prevent fragments from being written there, you could provide the parametric form to the fragment shader and simply discard while outside, or maybe an SDF?

You're right on track with what I'm thinking. Again, in early stages, but I plan on using something like this already for a shape's own rejection of fragments. Doing also the parent's rejection... I need to think it through.
