<summary>
Returns the advances in design units for a sequences of glyphs.
</summary>
<param name="glyphCount">Number of glyphs to retrieve advances for.</param>
<param name="glyphIndices">Array of glyph id's to retrieve advances for.</param>
<param name="glyphAdvances">Returned advances in font design units for
each glyph.</param>
<param name="isSideways">Retrieve the glyph's vertical advance height
rather than horizontal advance widths.</param>
<remarks>
This is equivalent to calling GetGlyphMetrics and using only the
advance width/height.
</remarks>
<returns>
Standard HRESULT error code.
