/// \defgroup ExportMacros Macros to manage symbol visibility
///
/// See website/SymbolVisibility.rst for more discussion about the
/// motivation for these macros
///
/// If we are compiling a DLL for Windows, there needs to be custom
/// rules for each library such that the macro swaps between doing a
/// dllexport and a dllimport, so the defines here are less
/// useful. Further, MSVC does not have this concept at all currently,
/// so is elided.
///
/// The top level macros which start with OPENEXR can act as simple
/// ways to combine the logic however for non-DLL or non-windows
/// platforms, but until the current patterns change, one should check
/// the specific library export.h (i.e. @sa IexExport.h,
/// @sa IlmThreadExport.h, @sa ImfExport.h, @sa ImfUtilExport.h )
///
/// These per-library exports define a subset which are used by that
/// library.
///
/// Iex is simple and does not need to do more than expose class types
/// and functions, and does not have any private members to hide, so
/// only provides a couple of the possible macros.
///
/// Similarly, IlmThread is also reasonably simple.
///
/// OpenEXR and OpenEXRUtil have much more logic and have to deal with
/// templates and template instantiation, and so define more of the
/// macros.
