If two partially opaque shapes overlap, can I show only one shape where they overlap?

Question

For example if you have a simple \"spy glass\" shape made of a circle and a rectangle and the outlines of both are partially transparent, can you stop the opacity effectivel

Answer 1

If the shape is constructed as a single SVG path element, the overlaps don't sum up into a darker result.

If the shape is constructed of multiple SVG elements, the overlaps do sum up into a darker result.
