  lpng implements loading of truecolor PNG images (with or 
  without an alpha channel) into 32-bit (RGB+A) Windows 
  bitmaps that can be used with AlphaBlend function.

  The .exe of a sample application is only 16KB in size,
  with 3KB taken by the actual PNG stored as resources.

  The API consists of just one function:

    HBITMAP LoadPng(const wchar_t * resName,
                    const wchar_t * resType,
                    HMODULE         resInst,
                    BOOL   premultiplyAlpha);

  It can be used to load a PNG from a disk file or from 
  a resource. Sample application demonstrating the use of 
  the API can be found in ./sample directory. The project 
  file is for Visual Studio 2005.

  The "premultiply" parameter controls whether the pixels'
  RGB values are 'pre-multiplied' at respective alpha value 
  if the alpha channel is present. This is a pre-processing
  step requied by the AlphaBlend function, so the parameter
  needs to be TRUE if the bitmap is going to be painted on
  a target DC using this function. Otherwise, e.g. if the
  bitmap is going to be used for an ImageList, it needs to
  be FALSE.
