PDF: Add simple implementation of _cairo_pdf_surface_show_glyphs (text as paths).
This isn't very exciting text output---it simply turns every call to cairo_show_glyphs into a single filled path. But at the very least, text will no longer trigger image fallbacks for the PDF backend. With this commit, the following tests change from all-fallback to all-native for the PDF backend: show-text-current-point text-antialias-gray text-antialias-none text-antialias-subpixel text-cache-crash text-rotate There are rasterization differences in the output (cairo vs. freetype) so this commit also adds new PDF-specific reference images for some of those tests so that the suite continues to report PASS.
