And here's the first bug report after applying this patch:
emacs -Q
M-: (w32-find-non-USB-fonts) RET
This pops up the Emacs Abort dialog. The backtrace and some
additional information are below. The error from
GetGdiCompatibleGlyphMetrics (0x80070057) seems to be E_INVALIDARG.
Perhaps if w32_dwrite_text_extents fails, it should not abort, but
instead fall back on the old code?
If you cannot reproduce this (maybe it depends on what fonts are
installed), feel free to ask me to provide more information or try
some solutions. In case it matters, this is a 32-bit build configured
as --with-wide-int --without-native-compilation.
Thread 1 received signal SIGTRAP, Trace/breakpoint trap.
