// Description:
//    These are all of the blt routines that are available.  It is assumed
//  that clipping and parameter checking has already occurred.
//
// History:
// -@- 09/23/97 (mikemarr) copied to DXCConv from d2d\mmimage
// -@- 10/28/97 (mikemarr) added colorfill routines
// -@- 10/28/97 (mikemarr) added HasPixelFn/ColorFillFn arrays
