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)
