OK, so let's call GetOutlineTextMetricsW and GetTextMetricsW in Emacs
through function pointers, like the sample program did.  Let's see if
that works.  You will need to declare hm_unicows `extern' in w32font.c
and give it global scope in w32.c.  Then copy the code from the sample
program that calls these function through function pointers, viz.

  len = s_pfn_Get_Outline_Text_Metrics_W (dc, 0, NULL);

(and similarly for the other calls) into w32font_open_internal, and
see if it starts working.

Thanks.
