I use 1.5 scaling factor on my PC and the cursor sizes 24 (factor 1) and 48 (factor 2) were both not really suitable. I think adding a 1.5 cursor is a good move, since it is a common scaling factor and we only have two Breeze (Snow) cursor sizes until now anyway.
Rebuilt everything with the script, which also replaced some unnecessary copies with symlinks.
