* MatchImage
*
* This function takes LPINTs for width & height in case of "real size".

*
* Returns a number that measures how "far away" the given image is
* from a desired one.  The value is 0 for an exact match.  Note that our
* formula has the following properties:
*     (1) Differences in width/height count much more than differences in
*         color format.
*     (2) Bigger images are better than smaller, since shrinking produces
*         better results than stretching.
*     (3) Color matching is done by the difference in bit depth.  No
*         preference is given to having a candidate equally different
*         above and below the target.
*
* The formula is the sum of the following terms:
*     abs(bppCandidate - bppTarget)
*     abs(cxCandidate - cxTarget), times 2 if the image is
*         narrower than what we'd like.  This is because we will get a
*         better result when consolidating more information into a smaller
*         space, than when extrapolating from less information to more.
*     abs(cxCandidate - cxTarget), times 2 if the image is
*         shorter than what we'd like.  This is for the same reason as
*         the width.
*
* Let's step through an example.  Suppose we want a 4bpp (16 color),
* 32x32 image.  We would choose the various candidates in the following order:
* 
* Candidate     Score   Formula
*
* 32x32x4bpp  = 0       abs(32-32)*1 + abs(32-32)*1 + 2*abs(4-4)*1
