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.
#include <stdio.h>
#include <assert.h>
#include <limits.h>

/**
* KiROUND
* rounds a floating point number to an int using
* "round halfway cases away from zero".
* In Debug build an assert fires if will not fit into an int.

*) for footprint access into *.mod files and
*) BOARD save/load
The item_io.cpp and ioascii.cpp have been set off to the side for reference
as *.notused, for awhile.
The CMake options USE_NEW_PCBNEW_LOAD and USE_NEW_PCBNEW_SAVE are gone,
this is now the mandatory usage of the LEGACY_PLUGIN. This should reduce
code maintenance for awhile until the s-expression plugin comes into
play. But at least for legacy format, there is not two code bodies
to maintain any more.
A new LEGACY_PLUGIN footprint library caching scheme is in place which
needs some testing. It should not be any faster, but might give better
results in a networked environment if there is *.mod files on the server.
* Remove internal units from BASE_SCREEN and it's derivatives.
* Remove internal units from EDA_DRAW_FRAME and it's derivatives.
* Use build time code to replace internal units conversions.
* Fix scaling bug in page layout sample window that I created in my
last commit.
* Move all convert from user to internal units into base_units.cpp.
* Remove internal units parameters from all moved conversion functions.
* Revise all source code that calls the moved conversion functions.
* Remove internal units from all dialog text control helper classes.
* Move all convert from internal to user units functions into separate file.
* Remove internal units parameter from all moved conversion functions.
* Revise all source code that calls the moved conversion functions.
* Compile these conversion routines separately for the appropriate pcb or
schematic internal units.
* Move internal units specific status bar update code into the appropriate
application for updating the status bar.
* Move millimeter user units rounding function to common.cpp.
* Move EDA_TEXT object into separate header and source file.
* Compile EDA_TEXT class separately for BOARD_ITEM and SCH_ITEM units.
* Compile PAGE_INFO class separately for BOARD_ITEM and SCH_ITEM units.
* Minor formatting tweaks to Pcbnew s-expression file.
* Move internal unit formatting functions into BOARD_ITEM and SCH_ITEM.
* Fix bug in PCBNEW dialog_pad_properties.cpp that I introduced several days ago.
The m_Master_Pad stuff is stored in the PCB_EDIT_FRAME's BOARD_DESIGN_SETTINGS,
not in the FOOTPRINT_EDIT_FRAME's BOARD_DESIGN_SETTINGS (i.e. not stored in
the module editor's dummy BOARD). Now we properly initialize the
DIALOG_PAD_PROPERTIES::m_Pad_Master reference to the correct master pad
dope, instead of to the dummy module BOARD's master pad, which is not used.
* Save dialog now supports saving boards to new file format.
* Add CMake option to build s-expression file save.
* Add check to main CMakeList.txt file to make sure nanometers are
enables when the new file format is built.
* Minor tweaks to object format functions for improved output.
* Rename kicad_plugin.h/cpp to legacy_plugin.h/cpp.
This uses the new LEGACY_PLUGIN, so we can force more usage & testing of it
before ioascii.cpp and item_io.cpp are deleted, along with
BOARD_ITEM::Save() and BOARD_ITEM::ReadDescr() associated functions.
