    Is there anyway to display a 24bpp DIB on a 256 color SVGA without
    implementing the code for color quantization?  I wrote some code to
    convert 24bpp images into 8bpp DIBs, but it takes around 10 seconds
    for a 512x512 DIB, and I just wonder if there is a better way.

    I did try using SetDIBitsToDevice, but the picture only uses the 20
    system colors to draw the 24bpp DIB.  The result is pretty nasty looking.

    So, I would be intereseted in hearing how other people got around the
    problem of using 24bpp DIBs on a 256 color system.  Thanks!
