*
* Sets the filter to be used for resizing when using this pattern.
* See #cairo_filter_t for details on each filter.
*
* * Note that you might want to control filtering even when you do not
* have an explicit #cairo_pattern_t object, (for example when using
* cairo_set_source_surface()). In these cases, it is convenient to
* use cairo_get_source() to get access to the pattern that cairo
* creates implicitly. For example:
*
* <informatlexample><programlisting>
* cairo_set_source_surface (cr, image, x, y);
* cairo_pattern_set_filter (cairo_get_source (cr), CAIRO_FILTER_NEAREST);
* </programlisting></informatlexample>
