/**
@brief Any scene converter plugin
@m_since{2020,06}

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

-   Stanford (`*.ply`), converted with @ref StanfordSceneConverter or any other
    plugin that provides it

Only converting to files is supported.

@section Trade-AnySceneConverter-usage Usage

This plugin depends on the @ref Trade library and is built if
`MAGNUM_WITH_ANYSCENECONVERTER` is enabled when building Magnum. To use as a
dynamic plugin, load @cpp "AnySceneConverter" @ce via
@ref Corrade::PluginManager::Manager.

Additionally, if you're using Magnum as a CMake subproject, do the following:

@code{.cmake}
set(MAGNUM_WITH_ANYSCENECONVERTER ON CACHE BOOL "" FORCE)
add_subdirectory(magnum EXCLUDE_FROM_ALL)

# So the dynamically loaded plugin gets built implicitly
add_dependencies(your-app Magnum::AnySceneConverter)
@endcode

To use as a static plugin or as a dependency of another plugin with CMake, you
need to request the `AnySceneConverter` component of the `Magnum` package and
link to the `Magnum::AnySceneConverter` target:

@code{.cmake}
find_package(Magnum REQUIRED AnySceneConverter)

# ...
target_link_libraries(your-app PRIVATE Magnum::AnySceneConverter)
@endcode

See @ref building, @ref cmake, @ref plugins and @ref file-formats for more
information.

@section Trade-AnySceneConverter-proxy Interface proxying and option propagation

On a call to @ref convertToFile(), a target file format is detected from the
extension and a corresponding plugin is loaded. After that, flags set via
@ref setFlags() and options set through @ref configuration() are propagated to
the concrete implementation, with a warning emitted in case given option is not
present in the default configuration of the target plugin.

The output of the @ref convertToFile() function called on the concrete
implementation is then proxied back.
