-<p>Set the horizontal and vertical resolution for image fallbacks.</p>
-<p>When certain operations aren't supported natively by a backend,
-cairo will fallback by rendering operations to an image and then
-overlaying that image onto the output. For backends that are
-natively vector-oriented, this function can be used to set the
-resolution used for these image fallbacks, (larger values will
-result in more detailed images, but also larger file sizes).</p>
-<p>Some examples of natively vector-oriented backends are the ps, pdf,
-and svg backends.</p>
-<p>For backends that are natively raster-oriented, image fallbacks are
-still possible, but they are always performed at the native
-device resolution. So this function has no effect on those
-backends.</p>
-<p>Note: The fallback resolution only takes effect at the time of
-completing a page (with <a class="link" href="cairo-cairo-t.html#cairo-show-page" title="cairo_show_page ()"><code class="function">cairo_show_page()</code></a> or <a class="link" href="cairo-cairo-t.html#cairo-copy-page" title="cairo_copy_page ()"><code class="function">cairo_copy_page()</code></a>) so
-there is currently no way to have more than one fallback resolution

-<p>Even if a backend supports a MIME type, that does not mean cairo
-will always be able to use the attached MIME data. For example, if
-the backend does not natively support the compositing operation used
-to apply the MIME data to the backend. In that case, the MIME data
-will be ignored. Therefore, to apply an image in all cases, it is best
-to create an image surface which contains the decoded image data and
