X Title: MAINT: Deterministic SVG and PDF tests by jkseppan · Pull Request #7748 · matplotlib/matplotlib

Description: There has been plenty of work (at least #4434, #5671, #5766, #6597) to make it possible to have deterministic svg and pdf output, or at least closer to deterministic than before. This change adds one related feature: callers can remove the bits of pdf metadata that contain the date and matplotlib version, so that new releases don't necessarily change the result of every test. Furthermore, this change enables all the optional pdf and svg determinism features in tests. I am developing some improvements to test-result caching on another branch, and in my tests only the following test files still change from run to run after this patch (although in my environment I get KNOWNFAIL=27, SKIP=8 so some more are possible): clip_path_clipping.svg hatching.svg pgf_bbox_inches.pdf pgf_mixedmode.pdf pgf_pdflatex.pdf pgf_rcupdate1.pdf pgf_rcupdate2.pdf pgf_xelatex.pdf bbox_inches_tight_clipping.svg image_clip.svg scaled_lines.svg offsetbox_clipping.svg skew_axes.pdf skew_axes.svg
