I should emphasize the *right now* part, because I want to add an
"embedded-svg" stencil expression that would only be valid for the SVG
backend, thus causing crashes in the PostScript backend.

In the future, I hope we can have real regression tests for the SVG
backend.  This would require an output-preview-framework and an
external tool to convert SVG->PNG.

In this case, any regtest that uses "embedded-svg" that accidentally
uses the PostScript backend will fail, and the appropriate changes can
be made to the regtest.
