<summary>
Obtains design units and common metrics for the font face.
These metrics are applicable to all the glyphs within a fontface and are used by applications for layout calculations.
</summary>
<param name="emSize">Logical size of the font in DIP units. A DIP ("device-independent pixel") equals 1/96 inch.</param>
<param name="pixelsPerDip">Number of physical pixels per DIP. For example, if the DPI of the rendering surface is 96 this
value is 1.0f. If the DPI is 120, this value is 120.0f/96.</param>
<param name="transform">Optional transform applied to the glyphs and their positions. This transform is applied after the
scaling specified by the font size and pixelsPerDip.</param>
<param name="fontFaceMetrics">Points to a DWRITE_FONT_METRICS structure to fill in.
The metrics returned by this function are in font design units.</param>
