dcpomatic/test, branch v2.17.18

Simplify the FontIDAllocator a lot (#2827).

2024-06-11T07:52:28Z

This is at the expense of forward compatibility, and the need to re-examine subtitle content (losing custom fonts as we do so). But it does mean that the code is simpler, and there's not this weird growth of IDs where a DCP gets imported with some font, and then the ID becomes 0_font, and if you do it again it's 0_0_font, and so on.

Fix an erroneous font ID error that can happen when loading projects from builds without release version tags.

So that last_written_by_earlier_than() always returns true, check_font_ids() happens when it doesn't really need to.

Fix font ID allocation from DCP when there are subs and ccaps using the same IDs (#2822).

2024-06-07T19:09:03Z

Previously we would always use _id as a disambiguated ID for every case.

Bump test/data for another subtitle rendering reference fix.

Render subtitles using show_in_cairo_context() instead of add_to_cairo_context().

2024-05-30T17:59:06Z

This helps with #2813 and should fix #2474. We started using add_to_cairo_context() again in 72c3a5f0f32f553a1f8abee2494f31d29b976383 because the rendering looked better. However colour changes within lines cannot easily be rendered using add_to_cairo_context() it seems, as the text is just added as a path and then you can stroke/fill it with a single colour. I hope that this change, which reverts 72c3a5 but also adds some calls to enable hinting and use better anti-aliasing, looks OK. I looked at some white-on-black subs close-up and the hinting seems to help.

Fix merge.
