Is it possible to achieve the same as these 2 hunks at a higher level
through the use of cairo_pattern_set_filter(CAIRO_FILTER_NEAREST) or
cairo_pattern_set_filter(CAIRO_FILTER_FAST) ? It does not seem to be
possible to get kCGInterpolationLow from _cairo_quartz_filter_to_quartz
at this point though.
