/**
@brief Any shader converter plugin
@m_since_latest

@m_keywords{AnyShaderConverter}

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

-   GLSL (`*.glsl`, `*.vert`, `*.frag`, `*.geom`, `*.comp`, `*.tesc`, `*.tese`,
    `*.rgen`, `*.rint`, `*.rahit`, `*.rchit`, `*.rmiss`, `*.rcall`, `*.mesh`,
    `*.task`)
-   SPIR-V (`*.spv`)
-   SPIR-V Assembly (`*.spvasm`, `*.asm.vert`, ..., `*.asm.task`)

Supported validation scenarios:

-   GLSL, validated with any plugin that provides `GlslShaderConverter`
-   SPIR-V, validated with any plugin that provides `SpirvShaderConverter`
-   SPIR-V Assembly, validated with any plugin that provides
    `SpirvAssemblyShaderConverter`

Supported conversion paths:

-   GLSL to SPIR-V, converted with any plugin that provides
    `GlslToSpirvShaderConverter`
-   SPIR-V to SPIR-V, converted with any plugin that provides
    `SpirvShaderConverter`
-   SPIR-V to SPIR-V Assembly, converted with any plugin that provides
    `SpirvToSpirvAssemblyShaderConverter`
-   SPIR-V Assembly to SPIR-V, converted with any plugin that provides
    `SpirvAssemblyToSpirvShaderConverter`
-   SPIR-V Assembly to SPIR-V Assembly, converted with any plugin that provides
    `SpirvAssemblyShaderConverter`

Only validating and converting files is supported.

@section ShaderTools-AnyConverter-usage Usage

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

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

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

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

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

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

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

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