--------------------------------

  Changes in version 1.5:

- fixed loading of 1,2,4-bit per pixel paletted APNGs.

--------------------------------

  Usage (for command-line version): 

apng2gif anim.png [anim.gif] [/t tlevel] [/b bcolor]

  Options:

/t 128 

  will set the transparency threshold level as 128, so pixels 
  with alpha level less than 128 will become fully transparent.

/b #ff0000  
/b 255 0 0 

  will set the background color as red, so partially transparent 
  pixels will be composed over red. When /b is used, /t is ignored.

  When no options are specified, default threshold is 128, 
  no background color.
