1.15 4/18/97 John-Mark Gurney <gurney_j@resnet.uoregon.edu>

                           Added [SR]RGBMASKs ioctl for byte swapping.

 1.16          4/20/97    Randall Hopper <rhh@ct.picker.com>
                          Generalized RGBMASK ioctls for general pixel
                          format setting [SG]ACTPIXFMT, and added query API
                          to return driver-supported pix fmts GSUPPIXFMT.

 1.17          4/21/97    hasty@rah.star-gate.com
                          Clipping support added.

 1.18          4/23/97    Clean up after failed CAP_SINGLEs where bt
                          interrupt isn't delivered, and fixed fixing
                          CAP_SINGLEs that for ODD_ONLY fields.
