 * XCreateBitmapFromData: Routine to make a pixmap of depth 1 from user supplied 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.

 *    bit_order=LSBFirst
 *    byte_order=LSBFirst
 *    padding=8
 *    bitmap_unit=8
 *    xoffset=0
