@brief Support tables for widely used image, scene, audio and font formats

@tableofcontents

The @ref Audio::AnyImporter "AnyAudioImporter",
@relativeref{Trade,AnyImageImporter}, @relativeref{Trade,AnySceneImporter},
@relativeref{Trade,AnyImageConverter}, @relativeref{Trade,AnySceneConverter}
and @ref ShaderTools::AnyConverter "AnyShaderConverter" plugins
@ref plugins-aliases "described on the previous page" can be used for generic
handling of any of the formats they recognize and they'll proxy the operation
to a concrete plugin implementation.

To support diverse use cases, there's commonly more than one alternative
implementation for given format. The following tables list the most widely used
formats with corresponding plugin implementations and known caveats for each.
When one format is supported by more than one plugin, you can use
@relativeref{Corrade,PluginManager::AbstractManager::setPreferredPlugins()} to
prioritize a particular plugin implementation.

See the @ref file-formats-legend section at the bottom of the page for a
detailed explanation of the color-coded columns.

@section file-formats-image-importers Image importers

Together with @ref file-formats-scene-importers "scene importers" derived from
@ref Trade::AbstractImporter.

@section file-formats-legend Legend

The *Caveats* column lists known issues and limitations of each plugin, and is
color-coded for easier understanding. Note the caveats might get updated over
time as features get implemented, bugs fixed or new issues discovered.

-   @m_class{m-label m-default} **none** means there are no known issues or
    limitations.
-   @m_class{m-label m-success} **minor** means the known issues only affect
    rare corner cases and shouldn't be a problem in practice.
-   @m_class{m-label m-warning} **some** means it has limitations affecting
    certain use cases. You're encouraged to check the documentation to be
    sure these don't affect you.
-   @m_class{m-label m-danger} **severe** means it has known bugs and
    limitations and isn't guaranteed to be usable for generic file import. It
    might work for your concrete use case, but you're encouraged to pick an
    alternative, if possible.
-   @m_class{m-label m-dim} **unknown** means there were no documented issues
    for given file format and there isn't enough practical experience to say
    how well it works.

The *Dependencies* column shows what kind of dependencies the plugin relies on,
highlighting potential portability issues:

-   @m_class{m-label m-default} **none** means it's dependency-free, with all
    its internals following Magnum standards of high test coverage, stability,
    portability and documentation.
-   @m_class{m-label m-primary} **bundled** means the dependency is usually a
    single-file 3rd party library that's bundled in the repo, and thus with no
    extra work needed to get it running. It's also tested on all platforms as
    Magnum itself, which should mean no portability issues either.
-   @m_class{m-label m-success} **bundleable, tiny** means the
    dependency is external to the repository, but it's relatively small and
    thus has no considerable impact on build times or deployment size. It can
    be either found externally or embedded as a CMake subproject, which may
    simplify the building procedure. While no guarantees on its portability are
    given, small libraries are generally rather portable.
-   @m_class{m-label m-warning} **bundleable** means the dependency is external
    to the repository and has a significant size that may have impact on build
    times and deployment size. However it's still possible to embed it as a
    CMake subproject, which *could* simplify the building a bit.
-   @m_class{m-label m-warning} **external, tiny** means the dependency is
    external to the repository, it's relatively small but cannot be (or isn't
    tested to be) embedded as a CMake subproject, which makes it slightly
    harder to get running.
-   @m_class{m-label m-danger} **external** means the dependency is external
    to the repository, has a significant size that may have impact on
    deployment size, and cannot be (or isn't tested to be) embedded as a CMake
    subproject. No guarantees on portability whatsoever.

The *License* column shows the license of the plugin dependency, if there's
any. Like with all other @ref credits-third-party "3rd party components", each
plugin has a color-coded block showing the license, linking to its text and
mentioning requirements coming from the license:

-   @m_class{m-label m-primary} **light blue** marks public domain
    dependencies, which don't require anything from you in order to use them
    and put no restrictions on use
-   @m_class{m-label m-success} **green** marks licenses that make the
    dependency safe to use in a commercial setting without having to release
    your source code, usually requiring you to give attribution.
-   @m_class{m-label m-warning} **yellow** marks licenses that require you to
    either dynamically link to the software to be able to use it in a
    commercial setting or release your source code as well. Such plugins are
    safe to use in internal development tools and asset pipelines, but you
    might want to consider alternatives before bundling them in a deployed
    commercial product. In some cases there is an alternative commercial
    licensing option without this requirement.
-   @m_class{m-label m-danger} **red** label marks licenses that
    unconditionally require you to publish your software together with its
    source code. Such plugins are only safe to use in internal development
    tools and asset pipelines, consider alternatives for use in a deployed
    commercial product. In some cases there is an alternative commercial
    licensing option without this requirement.
