 * XCreatePixmapFromBitmapData: Routine to make a pixmap from user supplied
 * bitmap data. D is any drawable on the same screen that the pixmap will be
 * used in. Data is a pointer to the bit data, and width & height give the
 * size in bits of the pixmap. Fg and Bg are the pixel values to use for the
 * two colors. Depth is the depth of the pixmap to create.
 * 
 * The following format is assumed for data:
 * 
 * format=XYPixmap bit_order=LSBFirst byte_order=LSBFirst padding=8
 * bitmap_unit=8 xoffset=0 no extra bytes per line
