Required for vgk.sys (vanguard anti-cheat).

For example, queueing a MF_SOURCE_READERF_ENDOFSTREAM response will set
a NULL sample. This fixes a regression introduced by commit

Fix the corresponding message sequences.

When height > 0, CreateFontA/W() should not return a font face exceeding the requested height.
For instance, Tahoma has 2049 units of ascent, 423 units of descent and its units per EM square is
2048. When requesting a font 20 pixels in height, ppem = units_per_EM * requested_height / (ascent + descent)
= 2048 * 20 / (2049 + 423) = 16.57 ~= 17. When getting the resulting height back from the ppem,
resulting_height = (ascent + descent) * ppem / units_per_EM = (2049.0 + 423) * 17 / 2048 = 20.52
~=21. So it ends up getting a larger font than requested and violates the spec.
