  Log:
  Add port graphics/tkpng:
  
  This port implements support for loading and using PNG images with
  Tcl/Tk.  Although other extensions such as Img also add support for PNG
  images, I wanted something that was lightweight, did not depend on libpng,
  and which would be suitable for inclusion in the Tk core, as Tk does not
  currently support any image formats natively that take advantage of its
  internal support for alpha blending, and alpha antialiasing and drop shadows
  really go a long way toward beautifying Tk applications.
  
  At this time, the package supports reading images from files or binary
  data.  Base64 decoding is supported as of version 0.6.  Exporting images
  to PNG format is not supported yet.
  
  The package supports the full range of color types, channels and bit
  depths from 1 bit black & white to 16 bit per channel full color
  with alpha (64 bit RGBA) and interlacing.  Ancillary "chunks" such
  as gamma, color profile, and text fields are ignored, although they
  are checked at a minimum for correct CRC.
