To get rid of the "libpng warning: iCCP: known incorrect sRGB profile" use:

find . -name '*.png' -print -exec mogrify -strip {} \;

mogrify is from ImageMagick which can be installed on ubuntu/wsl using "sudo apt-get install imagemagick"

hdf5 library was a pain to compile. I ended up building it using Cmake on Windows to get the required H5pubconf.h file and running a build under VS2015 to generate the required H5lib_settings.c and H5Tinit.c. My guess is that this will need to be redone (probably using configure and make) for a Mac build.

Fonts in the icons are mostly in the Segoe family but converted to outlines for portability

Once these are normalised then the Matlab and the GalenQt eigenvectors are the same but oddly they are not sorted in the right order. Matlab 1 & 2 equates to GalenQt 2 & 1. And I'm pretty sure that Matlab is right since its image 1 contains the overtext. They are also reversed but that doesn't matter.
