Now the glyph outline is inspected directly to get its real size,
as the direct measuring functions give generic values for some
fonts.
* src/w32dwrite.c (data structures): Added data structures from
header files that are not present in the 32bit MinGW build
environment.
(text_extents_internal): Call GetGlyphRunOutline to get exact
glyph vertical bounds. Add new parameter to make this optional
if case that information is not required.
(w32_dwrite_text_extents, w32_initialize_direct_write)
(w32_dwrite_draw): New parameter for 'text_extents_internal'.
(Bug#77171)

* src/w32dwrite.c (text_extents_internal): Return false instead
of crashing with bad glyph indexes. (Bug#77196)

Run "TZ=UTC0 admin/update-copyright".

* src/pdumper.c (dump_mm_heap_cb_release): Avoid NULL pointer
dereference.
* src/w32dwrite.c (INITGUID) [CYGWIN]: Don't define for Cygwin.
* src/w32menu.c (w32_popup_dialog): Fix Cygw32 build. (Bug#74312)

Negative lbearings were not handled.

lbearing.

This adds support for color fonts.
* configure.ac: Add src/w32drite to W32_OBJ.
* src/w32dwrite.c: New file.
(w32-initialize-direct-write): New function, initialize the
DirectWrite library if it is available, and required global
variables.

is available and activated by the user.
(w32_dwrite_encode_char): New function, replacement for HarfBuzz's

(release_com): New function, release a COM object.
(w32-dwrite-available): New function, returns true if DirectWrite
is available.
(w32-dwrite-reinit): New function, reinitialize DirectWrite,
