Dick Hollenbeck c24863c078 // Dick Hollenbeck's KiROUND R&D
// 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.

Wayne Stambaugh c2e5fcaec8 More encapsulation improvements.
* EDA_DRAW_FRAME completely encapsulated.
* Encapsulate the the low hanging fruit in EDA_DRAW_PANEL.

Wayne Stambaugh 4b853dedb4 Application name capitalization fixes.
* Correct all user strings and comments for the correct capitalization of
  application names according to JP.  They are KiCad, Pcbnew, CvPcb,
  Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.

Wayne Stambaugh edd35b4e90 PCB common library header rationalization.
* All header files used to create the PCB common library now compile as
  stand alone code.  This prevents the need to define them in a specific
  order to make source code compile properly.  It should also now be
  possible to relocate the source code to build the common PCB library
  to a separate folder.
