Adding to Thomas answer: the larger integer size in CPUs being 64 bit
has absolutely nothing to do with the pixel depth a program can use.
One could write a program to manipulate images in which each pixel was
represented by a 5 X 64 bit in an 8 bit machinne.
But, answering you both: yes, current gimp trunk is using GEGL for
some color operations, which are them performed at 32bit floating
point precision. Version 2.6, which will come out this year will
implement that, but likely it won support saving in more than 8bit
If you are working with monochrome, and 16 bit final output formats
would indeed make a difference, I suggest increasing your resolution
by a factor of 2 or 4 to overcome this.
