Detail:
  In 1/2/4bpp modes the loop could potentially read off the end of the input buffer
  (causing an abort if the next page isn't mapped in), or cause the rightmost column to be
  lost.
  Refactor the loop to count in destination bits to avoid both problems.

Version 0.06. Not tagged

Detail:
* Honours the bit depth of the source image rather than setting 8bpp flat.
  This is based on the palette size and is now restricted to 2, 4, 16 or
  256 colours.  Non-paletted images are 24 bit colour.
* Add option to add tRNS chunk for paletted images to have a mask set by
  substituting one of the paletted entries for a transparency.
* Change palette docs in CompressPNG - 0x00BBGGRR not just a 3 byte entity.
* Refuse to start a compression run if ZLib module is missing.
