Expand description

Get the default media (not plot) blitter for this environment when using the specified scaling method. Currently, this means:

  • if lacking UTF-8, NCBLIT_1x1
  • otherwise, if not NCSCALE_STRETCH, NCBLIT_2x1
  • otherwise, if sextants are not known to be good, NCBLIT_2x2
  • otherwise NCBLIT_3x2 NCBLIT_2x2 and NCBLIT_3x2 both distort the original aspect ratio, thus NCBLIT_2x1 is used outside of NCSCALE_STRETCH.
