Review on #4831 pointed out the PDF Association's erratum to ISO 32000-2
(pdf-association/pdf-issues #368): inside a text object, q/Q also save and
restore Tm and Tlm (§9.4.1, referenced from §8.4.2). Acrobat 26.2 agrees on
a synthetic PDF 2.0 page. The renderer on main already did this, so the
previous commit's hayro-interpret patch (67) was wrong: it is reverted here,
with its vendor/README row and the render tests.
The real disagreement was in the redactor's own interpreter, which kept Tm
and Tlm across Q. Find took its boxes from the renderer's text, the redactor
measured the glyphs elsewhere, and redact_apply refused on residue. Its
state stack now holds (Gs, Tm, Tlm) and Q restores all three.
Test: it::redact_text_after_q, end to end on %PDF-2.0 fixtures, three cases
(font change inside q/Q; q 100 0 Td Q; the same followed by T*). With the
redactor change reverted, each case fails on its own at redact_apply. With
only Tm restored, the T* case fails.

Review on #4862 found two mismatches between the on-page field editor and
the field's appearance:
- Comb fields: the editor sized them as single-line text (20.87 pt for a
500 x 30 comb) while the appearance uses 4-12 pt from the cell height.
The comb test is now `Field::is_comb` and the comb size
`appearance::comb_auto_text_size`, both shared by the appearance and
`forms_ui::field_text_size`. The editor's test was looser (it ignored
Multiline and Password); it now matches the page's.
- Tall fields: `field_text_size` capped at 300 pt and the three call sites
clamped the screen font to 64. Both are gone; `field_screen_font` scales
by zoom and bounds the result at MAX_SCREEN_FONT (256 screen points) so a
glyph stays well inside the font atlas.
A non-finite comb height now gives 4 pt, as single-line auto-size does.
Test: it::forms::the_field_editor_sizes_auto_size_text_as_the_page_does.
With the comb change reverted the comb assertion fails (20.87 vs 12); with
the 300/64 caps restored the 100 pt assertion fails.
Also fixes it::forms::dragging_over_another_fields_text_focuses_it_and_selects_from_the_press,
which the previous commit broke: the name field now auto-sizes to 13.9 pt
instead of 12, so the press point 30 px in fell on "A|da"; it is now 38 px
in, inside "Ad|a" as the test intends.
