View source for MatlabPyrTools patch

The HDR-VDP-2 requires that [http://www.cns.nyu.edu/~lcv/software.php matlabPyrTools] are used with the compiled MEX files and not the default .m matlab scripts. This is because .m and MEX files return slightly different results, while the HDR-VDP-2 was calibrated for the MEX files.

Version 1.4 of matlabPyrTools fails on recent version of matlab when used with MEX files. The attached [http://hdrvdp.sourceforge.net/matlabPyrTools_1.4_upConv.patch patch] resolves this issue.
