* <pre>
* This file is here to describe the fields in the header of
* the BMP file. These fields are not used directly in Leptonica.
* The only thing we use are the sizes of these two headers.
* Furthermore, because of potential namespace conflicts with
* the typedefs and defined sizes, we have changed the names
* to protect anyone who may also need to use the original definitions.
* Thanks to J. D. Bryan for pointing out the potential problems when
* developing on Win32 compatible systems.
* </pre>
