X Title: Fix support for empty usetex strings. by anntzer · Pull Request #16410 · matplotlib/matplotlib

Description: Currently, figtext(.5, .5, "%foo", usetex=True) results in an obscure exception (FileNotFoundError: No such file or directory: blah.dvi). Fix that by forcing tex to always generate a page, by inserting at least an empty \hbox{}. Closes #16409. Edit: looks like this shifts some tex strings a tiny bit, but I already have another patch which shifts them more -- specifically, a followup to #16373 which actually gives correct baselines even without using tex.latex.preview. So I'll just wait for that. PR Summary PR Checklist Has Pytest style unit tests Code is Flake 8 compliant New features are documented, with examples if plot related Documentation is sphinx and numpydoc compliant Added an entry to doc/users/next_whats_new/ if major new feature (follow instructions in README.rst there) Documented in doc/api/api_changes.rst if API changed in a backward-incompatible way
