   WBMP: Wireless Bitmap Type 0: B/W, Uncompressed Bitmap
   Specification of the WBMP format can be found in the file:
   SPEC-WAESpec-19990524.pdf
   You can download the WAP specification on: http://www.wapforum.com/

gd_wbmp.c

Fixed: gdImageWBMPPtr, gdImageWBMP

Recoded: gdImageWBMPCtx for use with my wbmp library
   (wbmp library included, but you can find the latest distribution
   at http://www.vandenbrande.com/wbmp)

Implemented: gdImageCreateFromWBMPCtx, gdImageCreateFromWBMP
