Changeset 25208 for trunk/Ohana/src/getstar/include/dvoImagesAtCoords.h

Timestamp:

Message:

swap order of loops to speed things up at least 25 %
Now do

for each image { check list of points for ovarlap }

instead of

foreach point { check list of images }

Since the number of images is large and there is some setup time for each
one this is faster
