-// FUNCTION : InitBitmapInfoHeader
-// PURPOSE : Does a "standard" initialization of a BITMAPINFOHEADER,
-// given the Width, Height, and Bits per Pixel for the DIB.
-//
-// By standard, I mean that all the relevant fields are set
-// to the specified values. biSizeImage is computed, the
-// biCompression field is set to "no compression," and all
-// other fields are 0.
-//
-// Note that DIBs only allow BitsPixel values of 1, 4, 8, or
-// 24. This routine makes sure that one of these values is
-// used (whichever is most appropriate for the specified
-// nBPP).
-//
-// PARMS : lpBmInfoHdr == Far pointer to a BITMAPINFOHEADER structure
-// to be filled in.
-// dwWidth == Width of DIB (not in Win 3.0 & 3.1, high
-// word MUST be 0).
-// dwHeight == Height of DIB (not in Win 3.0 & 3.1, high
-// word MUST be 0).
-// nBPP == Bits per Pixel for the DIB.
