Typo where constant should follow config variable?

[Nickson Yap]

Was going through the source code and found this line

OpenPano/src/stitch/transform_estimate.cc

Line 46 in ed87d3c

 ransac_inlier_thres = (shape1.w + shape1.h) * 0.5 / 800 * RANSAC_INLIER_THRES; 

It's quite weird for the number 800 to appear here only
Probably it should be replaced with SIFT_WORKING_SIZE?
I'm really unsure

OpenPano/src/config.cfg

Line 19 in ed87d3c

 SIFT_WORKING_SIZE 800	# working resolution for sift 

Such that it from:

ransac_inlier_thres = (shape1.w + shape1.h) * 0.5 / 800 * RANSAC_INLIER_THRES;

to:

ransac_inlier_thres = (shape1.w + shape1.h) * 0.5 / SIFT_WORKING_SIZE * RANSAC_INLIER_THRES;

The 800 here is unrelated to SIFT_WORKING_SIZE. It's merely a parameter and it can already be tuned by tuning RANSAC_INLIER_THRES.
