 311                 pixel format are:
 312                     - aHidd_BitMap_ModeID:      a modeid. create a nondisplayable
 313                             bitmap with the size  and pixelformat of a gfxmode.
 314                     - aHidd_BitMap_StdPixFmt: a standard pixelformat as described in
 315                             hidd/graphics.h
 316                     - aHidd_BitMap_Friend: if this is supplied and none of the two above
 317                         are supplied, then the pixel format of the created bitmap
 318                         will be the same as the one of the friend bitmap.
 319
 320                 These tags are listed in prioritized order, so if
 321                 the user supplied a ModeID tag, then you should not care about StdPixFmt
 322                 or Friend. If there is no ModeID, but a StdPixFmt tag supplied,
 323                 then you should not care about Friend because you have to
 324                 create the correct pixelformat. And as said above, if only Friend
 325                 is supplied, you can create a bitmap with same pixelformat as Frien
