Selects the font into the given device context and changes the
map mode and world transformation of the device context to match
that of the font. This function is intended for use when using
layout APIs such as Uniscribe to do text layout with the
cairo font. After finishing using the device context, you must call

coordinates from the device context to font space.

Normally, calls to <code class="function">SaveDC()</code> and <code class="function">RestoreDC()</code> would be made around
the use of this function to preserve the original graphics state.
