Quartz port of 1.1: 

- changed 'innards' function to work the right way. Much faster now (see
  color_chooser for a test)
I won't be able to continue on the Quartz port for now. Please let me know
of issues not mentioned in previous commits and I will try to find the
time for fixes and improvements.
