- the cpp command is used to process Make/{files,options}, but builtin
  defines such as `linux` will cause problems (macro replacement) if
  these is present in the Make/{files,options}.

  Solve by undefining -Ulinux, -Uunix macros, which will leave directory
  names such as "/usr/lib/x86_64-linux-gnu/..." intact.

  Directories with _linux, __linux__ content (for example), could
  still pose future issues.

- as an alternative output transform (supplementary to the regular
  coordinate system specification - issue #2505) it is now possible to
  specify the rotation centre directly.

  Example:

      formatOptions
      {
          vtk
          {
              scale 1000;  // m -> mm
              transform
              {
                  origin  (0 0 0);
                  rotationCentre  (1 0 0);
                  rotation axisAngle;
                  axis    (0 0 1);
                  angle   -45;
              }
          }
      }

   This behaves like the transformPoints and surfaceTransformPoints
   '-centre' option (formerly '-origin') in that it removes the
   specified amount from the point locations, applies the rotation and
   finally adds the specified amount back to the newly rotated point
   locations.

   The results of specifying a `rotationCentre` and a non-zero
   coordinate system `origin` may not be intuitively evident.

- introduce a FOAM_LD_LIBRARY_PATH variable to shadow
  DYLD_LIBRARY_PATH on MacOS.

  The DYLD_LIBRARY_PATH and LD_LIBRARY_PATH cannot be modified via sub
  shells etc when SIP is active. This helps circumvent these
  restrictions, which is obviously a hack, but seems to be required.

COMP: disable -ftrapping-math in geompack for MacOS

- the output write scaling should be applied *after* undoing the
  effects of the specified rotation centre. Fixes #2566

ENH: update option names for transformPoints and surfaceTransformPoints

- prefer  '-auto-centre' and '-centre', but also accept the previous
  options '-auto-origin' and '-origin' as aliases.

  Changing to '-centre' avoids possible confusion with
  coordinate system origin().

The new algorithm introduces an optional entry 'nAlphaSmoothCurvature',
and aims to smooth interface curvatures to reduce spurious currents.

When a finite-area case could not find an entry for "lnGradSchemes"
in the "faSchemes" file, the "corrected" scheme has been picked up
by default. Therefore, any changes in "snGradSchemes" entry will not
be read by finite-area models.

- consistent with defining IO of int32_t/int64_t and with recent
  changes to ensightFile. Using the primitives directly instead of
  typedefs to them makes the code somewhat less opaque.

- they are/were identical to versions without an embedded '2'

- parse out symbols and use abi::__cxa_demangle for more readable
  names in safePrintStack.

- shorten prefixed /path/openfoam/platforms/lib/... to start
  with "platforms/lib/..." to avoid unreadably long lines.

- improved file-scope localization of helper functions.

STYLE: use std::ios_base::basefield instead of dec|oct|hex for masking

Probably can get away with less tetBasePtIs() triggering
