Switched image display function to absolute coordinates, which made it
easier to properly size and scale node images.
Merge branch 'master' of https://github.com/drghirlanda/mint
Moved from proportional to absolute coordinates in image functions,
simplified a number of things and corrected a few display bugs
Added '-' to the list of characters allowed in mint strings, used
in weight names (forgot about it!)
In network operate, moved weight update before node update as with named
nodes and weights there is no possibility to update nodes and weights in the
same spread step.
Removed a empty line :)
Created a headr for op type declaration, to make it visible to those
rare (and brave) functions that want to manipulate ops - used so far
only for multithreading
