/// Each imageio DSO/DLL should include this statement:
///      DLLPUBLIC int FORMAT_imageio_version = OPENIMAGEIO_PLUGIN_VERSION;
/// libOpenImageIO will check for compatibility this way.
/// This should get bumped any time we change the API in any way that
/// will make previously-compiled plugins break.
///
/// History:
/// Version 3 added supports_rectangles() and write_rectangle() to
/// ImageOutput, and added stride parameters to the ImageInput read
/// routines.
/// Version 10 represents forking from NVIDIA's open source version,
/// with which we break backwards compatibility.
/// Version 11 teased apart subimage versus miplevel specification in
/// the APIs and per-channel formats (introduced in OIIO 0.9).
/// Version 12 added read_scanlines(), write_scanlines(), read_tiles(),
///     write_tiles(), and ImageInput::supports(). (OIIO 1.0)
/// Version 13 added ImageInput::valid_file().  (OIIO 1.1)
/// Version 14 added ImageOutput::open() variety for multiple subimages.
/// Version 15 added support for "deep" images (changing ImageSpec,
///     ImageInput, ImageOutput).
/// Version 16 changed the ImageInput functions taking channel ranges
///     from firstchan,nchans to chbegin,chend.
/// Version 17 changed to int supports(string_view) rather than
///     bool supports(const std::string&)). (OIIO 1.6)
/// Version 18 changed to add an m_threads member to ImageInput/Output.
/// Version 19 changed the definition of DeepData.
/// Version 20 added FMT_imageio_library_version() to plugins. (OIIO 1.7)
/// Version 21 changed the signatures of ImageInput methods: added
///     subimage,miplevel params to many read_*() methods; changed thread
///     safety expectations; removed newspec param from seek_subimage;
///     added spec(subimage,miplevel) and spec_dimensions(subimage,miplevel).
///     (OIIO 1.9)
/// Version 22 changed the signatures of ImageInput/ImageOutput create()
///     to return unique_ptr. (OIIO 1.9)
