Gujarati text from a PDF came in jumbled even with its fonts installed: - A glyph with no advance (a vowel sign or anusvara set over its letter) was taken for vertical type and opened as an object of its own, which type then drew on a dotted circle. In a font the file writes horizontally it now stays on its line. - A line read glyph by glyph is not always the text that was set: the file draws a vowel sign before the consonant it follows, and may not name a conjunct. A line with characters of U+0900 to U+0DFF is now set again and its glyphs compared with the ink the file drew; when they differ the line keeps the file's glyphs as outlines, with a note. Tests: crates/pdf/src/tests/reshaped.rs (two fail without the change).
