/*
  COLORKEY_PIXEL_TOPLEFT is set when the animation has transparency
  and the transparent pixel color is the color of the topleft image
  pixel. For example, if the topleft pixel's color is 0x0000FF (blue),
  than all 0x0000FF (blue) pixels in the image are interpreted as
  transparent.

  MASK_PIXEL_COLORKEY is set when a mask should be constructed for the
  animation, and the mask should discriminate based on the colorkey.
  For example, if the colorkey is 0x0000FF (blue), than the mask should
  have OFF (0) in the mask for every 0x0000FF (blue) pixel, and ON (1)
  for every other pixel.
