[vtkusers] Suggested compile-time option

[johnny carroll norris]

Hi all,

When I'm compiling my app for release, I always call
wxObject::GlobalWarningDisplayOff().  Since this makes all the strings passed
to vtkWarningMacro and vtkErrorMacro so much wasted space, I've taken to
adding VTK_WARNING_ALWAYS_OFF, and using it to define vtkWarningMacro and
vtkErrorMacro (a la VTK_LEAN_AND_MEAN and vtkDebugMacro).  Under Solaris 2.7
using CC 5.0, this reduces the size of libVTKCommon.a, libVTKGraphics.a, and
libVTKImaging.a by over 1.7 MB total (from a total of 11,919 KB to 10,111 KB).
This represents a reduction in size of just over 15%.  I don't know how many
other programmers routinely call wxObject::GlobalWarningDisplayOff() in their
release builds, but if there are enough of us, it might be worthwhile to make
VTK_WARNING_ALWAYS_OFF a part of VTK.

Just a suggestion,
John
