Expand the virtual world to 2.14 meters in the nanometer build of PCBNEW.
This seems to be holding up for now.

Eeschema (also Libedit and Libview) now starts always to the default grid (50 mils)
Gerbview starts with the last selected grid, but the validity is tested.
In Pcbnew the grid value is always displayed, so it should always be good.

Delete LEGACY_PLUGIN cache after deleting library of same name.
Remove automatically generted freerouter help header.
Add Normalize() to BOX2.
Clamp some values in the virtual space of drawframe.cpp

Should allow Pcbnew code easier to change and Gerbview code more understandable and easier to maintain.
Code cleaning (remove dead code, add comments).
Minor other enhancements.

Other scaling factors (MILS_TO_IU_SCALING_FACTOR and DECIMILS_TO_IU_SCALING_FACTOR)
also defined only in convert_to_biu.h.
Allows different scaling value for Gerbview.
Needs more tests.

solution to see that it was not pre-computing constants when used in static initializers.

So we have two use cases, and need two solutions to be optimal, since the compiler 
is too stupid to do the right thing.

I think we need something else for compile time computable constants, to be optimal 
in both use cases.  There is quite a bit of code savings by using a macro for that 
situation from my testing.  To fully capitalize on this, we need to go back and make 
Mm2mils() and what not macros also, or have MACRO versions of them too.

  as a starting point
* Make double Distance() take double arguments and remove internal range checking.
* Start on EDA_DRAW_FRAME::AdjustScrollBars() and use "double" for most all calculations
  in anticipation of setting INT_MAX INT_MIN limits eventually.

* Move board item object Format() functions into PCB_IO object.
* Change file format to use layer names instead of numbers.
* Change file extension to kicad_pcb.

// This provides better project control over rounding to int from double
// than wxRound() did.  This scheme provides better logging in Debug builds
// and it provides for compile time calculation of constants.
