+ * 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

+/*! BMP file header
+ *
+ * Notes:
+ *  (1) The bfSize field is stored as a 32 bit integer and includes
+ *      the size of the BMP_FileHeader, BMP_InfoHeader, the color
+ *      table (if any), and the size of the DIB bits.
+ *  (2) The bfOffBits field is also stored as a 32 bit integer and
+ *      contains the absolute offset in bytes of the image data
+ *      in this file. Some bmp files have additional data after the
+ *      BMP_InfoHeader and before the color table (if it exists).
+ *      However, enabling reading of these files makes the reader
+ *      vulnerable to various malware attacks.  Therefore we do not
+ *      read bmp files with extra data, and require that the size
+ *      of the color table in bytes is
+ *         offset - sizeof(BMP_FileHeader) - sizeof(BMP_InfoHeader)
+ *  (3) Use arrays of l_uint8[] to make an endianness agnostic
+ *      access to the BMP_FileHeader easier.
