[numeric]  in/out X component of a distance vector

<code>dx</code>

[numeric]  yn/out Y component of a distance vector

<code>dy</code>

Transforms the distance vector (<code>dx</code>,<code>dy</code>) by <code>matrix</code>. This is
similar to <code><a rd-options="" href="/link/pangoMatrixTransformPoint?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::pangoMatrixTransformPoint">pangoMatrixTransformPoint</a></code> except that the translation
components of the transformation are ignored. The calculation of
the returned vector is as follows:
