• Mitchell - remapped pixels receive some
smoothing, plus blurring to hide pixelation.
• Bilinear - gives good results, but can produce
square artifacts at extreme zoom.
• Bicubic - provides more rounded results,
slightly blurrier but without the square
artifacts.
• Nearest - preserves edge detail, but gives
quite "blocky" textures.
