/**
@brief TGA importer plugin

Supports Truevision TGA (`*.tga`, `*.vda`, `*.icb`, `*.vst`) BGR, BGRA or
grayscale images with 8 bits per channel.

@section Trade-TgaImporter-usage Usage

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

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

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

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

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

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

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

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

@section Trade-TgaImporter-behavior Behavior and limitations

The images are imported with @ref PixelFormat::RGB8Unorm,
@ref PixelFormat::RGBA8Unorm or @ref PixelFormat::R8Unorm, respectively. Images
are imported with default @ref PixelStorage parameters except for alignment,
which may be changed to `1` if the data require it.

RLE compression is supported, paletted images are not.
