Cairo::Filter is used to indicate what filtering should be
applied when reading pixel values from patterns.
See Cairo::Pattern>>filter: for indicating the desired
filter to be used with a particular pattern.

similar to CAIRO_FILTER_NEAREST (Since 1.0)
CAIRO_FILTER_GOOD A reasonable-performance filter, with quality
similar to CAIRO_FILTER_BILINEAR (Since 1.0)
CAIRO_FILTER_BEST The highest-quality available, performance may not
be suitable for interactive use. (Since 1.0)
CAIRO_FILTER_NEAREST Nearest-neighbor filtering (Since 1.0)
CAIRO_FILTER_BILINEAR Linear interpolation in two dimensions
(Since 1.0)
CAIRO_FILTER_GAUSSIAN This filter value is currently unimplemented, and
should not be used in current code. (Since 1.0)
