I've been working on this problem on and off for over 10 years.

AMA ;-)

Are there any culling optimizations for unseen elements when layering SVG images? Looks like this isn’t an optimization that comes out-of-the-box with OpenVG and all the major web browsers needed to add this, so wondering what your solution is doing.

The depth buffer is used for opaque path interiors.

Does that mean there’s no culling for overlapping elements? Sorry, just trying to understand your response.
