Enum Members

Fast = 0: A high-performance filter, with quality similar to Filter::Nearest.
Good = 1: A reasonable-performance filter, with quality similar to Filter::Bilinear.
Best = 2: The highest-quality available, performance may not be suitable for interactive use.
Nearest = 3: Nearest-neighbor filtering.
Bilinear = 4: Linear interpolation in two dimensions.
Gaussian = 5: This filter value is currently unimplemented, and should not be used in current code.
