//----------------------------------------------------------------------------
// These macros may be used to deprecate APIs in VTK. They act as attributes on
// method declarations and do not remove methods from a build based on build
// configuration.
//
// To use:
//
// In the declaration:
//
// ```cxx
// VTK_DEPRECATED_IN_9_1_0("reason for the deprecation")
// void oldApi();
// ```
// or
// ```cxx
// class VTK_DEPRECATED_IN_X_Y_Z("reason for deprecation") OPT_EXPORT_MACRO oldClass {
// ```
//
// When selecting which version to deprecate an API in, use the newest macro
// available in this header.
//
// In the implementation:
//
// ```cxx
// // Hide VTK_DEPRECATED_IN_X_Y_Z() warnings for this class.
// #define VTK_DEPRECATION_LEVEL 0
//
// #include …
// ```
//
// Please note the `VTK_DEPRECATED_IN_` version in the `VTK_DEPRECATION_LEVEL`
// comment so that it can be removed when that version is finally removed. The
// macro should also be defined before any includes.
//----------------------------------------------------------------------------

// The level at which warnings should be made.
