  A. This is not possible. An Image with semi-transparency CANNOT be created at runtime.
  B. use createRGBImage() to create an immutable Image from ARGB data with the desired values
  C. use createImage() to create a mutable Image, then fill it with red pixels
  D. use createImage() to create a mutable Image; first fill it with white pixels, then fill it with red pixels
  B. use createRGBImage() to create an immutable Image from ARGB data with the desired values
