/**
@brief Any image converter plugin

Detects file type based on file extension, loads corresponding plugin and then
tries to convert the file with it.

This plugin is built if `WITH_ANYIMAGECONVERTER` is enabled when building
Magnum Plugins. To use dynamic plugin, you need to load `AnyImageConverter`
plugin from `MAGNUM_PLUGINS_IMPORTER_DIR`. To use static plugin, you need to
request `AnyImageConverter` component of `MagnumPlugins` package in CMake and
link to `MagnumPlugins::AnyImageConverter` target. See @ref building-plugins,
@ref cmake-plugins and @ref plugins for more information.

Supported formats for uncompressed data:

-   OpenEXR (`*.exr`), converted with any plugin that provides
    `OpenExrImageConverter`
-   PNG (`*.png`), converted with @ref PngImageConverter or any other plugin
    that provides it
-   TGA (`*.tga`), converted with @ref TgaImageConverter or any other plugin
    that provides it

No supported formats for compressed data yet.

Only exporting to files is supported.
