Behdad Esfahbod b51ab1a9e5 [cff] Optimize byte_str_ref_t 
Make it 16 bytes instead of 24.  This struct is used in the subroutine
call stack heavily.

This change makes the HB AdobeVFPrototype benchmark to become faster
than FT one, with about 6% speedup as a result of this change.

This reverts commit f657ef7e57.

This breaks many compilers with messages like this:

hb-subset-plan.hh:226: undefined reference to `OT::head::tableTag'

I'm out of my depth re how to fix it.

Martin Storsjö d88269c827 freetype: Fix function signatures to match without casts 
Clang 16 has got a new stricter warning for casts of function types
(see 1aad641c79).

This new warning gets included as part of the existing error
diagnostic setting of -Wcast-function-type.

This fixes errors like these:

../src/hb-ft.cc:1011:34: error: cast from 'void (*)(FT_Face)' (aka 'void (*)(FT_FaceRec_ *)') to 'FT_Generic_Finalizer' (aka 'void (*)(void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
    ft_face->generic.finalizer = (FT_Generic_Finalizer) hb_ft_face_finalize;
                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Marco Rebhan db292f6f02
Pass through absolute paths to cmake config directly 
The previous code concatenates includedir to _harfbuzz_prefix verbatim,
which results in a wrong final include path in case includedir is an absolute
path. Instead, we can let meson determine the absolute include and lib paths
in advance and save them in the cmake config.

This is an issue in nixpkgs, where includedir is set to the final (absolute)
path of the built library in the Nix store, which causes CMake projects
depending on harfbuzz to not configure.

See https://github.com/NixOS/nixpkgs/issues/180054.

Garret Rieger 70e2de2bd4 [subset] Always output Lookup's even if they are empty. 
The rest of layout subsetting depends on lookup indices being consistent with those computed during planning. So if an empty lookup is discarded during the subset phase it will invalidate all subsequent lookup indices. Generally we shouldn't end up with an empty lookup as we pre-prune them during the planning phase, but it can happen in rare cases such as when a subtable is considered degenerate (eg. #3853)

Garret Rieger 9559d3c1c1 [repacker] fix incorrect coverage table size estimation. 
During splitting of PairPosFormat2 the code was assuming the maximum size of the generated coverage table would be equal too the current size. This is incorrect size the new coverage table may not preserve the ranges found in the original coverage table (since we are splitting based on class, not coverage) and in the worst case may convert from format2 to format1. So use the size of a format1 table as the max size.

Garret Rieger 8f1bf23cc9 [subset] optimize glyf subsetting w/ retain gids. 
When retain gids is enabled the subset plan may require the output of many empty glyphs. This change optimizes the glyf subsetting code when the number of retained glyphs << number of output glyphs. Unnessecary lookups to the glyph map are reduced by iterating through the glyph map instead of the output glyph set.
