/**
* cairo_filter_t
* @CAIRO_FILTER_FAST: A high-performance filter, with quality similar
* to NEAREST
* @CAIRO_FILTER_GOOD: A reasonable-performance filter, with quality
* similar to BILINEAR
* @CAIRO_FILTER_BEST: The highest-quality available, performance may
* not be suitable for interactive use.
* @CAIRO_FILTER_NEAREST: Nearest-neighbor filtering
* @CAIRO_FILTER_BILINEAR: Linear interpolation in two dimensions
* @CAIRO_FILTER_GAUSSIAN: This filter value is currently
* unimplemented, and should not be used in current code.
*
* #cairo_filter_t is used to indicate what filtering should be
* applied when reading pixel values from patterns. See
* cairo_pattern_set_source() for indicating the desired filter to be
* used with a particular pattern.
