Parameters

img	Incoming image to match against.
mfImage	Buffer same size as img, to provide working memory for status of matched features.
xsize	Horizontal size of img and mfImage.
ysize	Vertical size of img and mfImage.
pixFormat	Pixel format of img.
mtemp	Template undergoing matching.
rx	search radius in x dimension.
ry	search radius in y dimension.
search	screen coordinates (second dimension is x and y) for up to three previous positions of this feature.
bx	On return, x position of best candidate.
by	On return, y position of best candidate.
val	On return, the quality of the match of the best candidate.
