But Inkscape supports masks ! You can define a vector object as a mask.
For example use a circle as a mask for a box so it has a hole, a bit like
include/exclude in CAD.
The feature most applicable is called "clipping paths", but yes. Masks are
similar, but rather than creating a sharp cutout based on the geometry of a path, they are
based on the path's rendering and can vary in intensity.
