Creates a pixmap and a mask bitmap which are returned in the <code>pixmap.return</code>
and <code>mask.return</code> arguments, respectively, and renders a pixbuf and its
corresponding tresholded alpha mask to them.  This is merely a convenience
function; applications that need to render pixbufs with dither offsets or to
given drawables should use <code><a rd-options="" href="/link/gdkDrawPixbuf?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::gdkDrawPixbuf">gdkDrawPixbuf</a></code>, and <code><a rd-options="" href="/link/gdkPixbufRenderThresholdAlpha?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::gdkPixbufRenderThresholdAlpha">gdkPixbufRenderThresholdAlpha</a></code>.
