Comment 14 for bug 699454

Looks like some good features, although it does potentially increase the number of ways to get gerber output wrong for the user!

Perhaps we should add some default button to the exporter which greys out the other options, and retains PCB's old ways for exporting.

Now we're using GIT, it should be really easy to produce a rebased patch series for these changes, complete with log entries (no /*... */ history comments in the code please!)

Looking at the code, and the list of features added, I think this could sensibly be more than one patch.

Refactor output precision code,
Add externally visible options for adjusting the output precision
Add metric support
Option to add outline to all layers
"disable drills output in outline layers" (Isn't this was already done?)

I've never personally come across any requirement to have X and Y axis resolutions different in the gerber file. I'm not sure it is a useful option to export.
