/**
@brief TGA importer plugin

Supports uncompressed BGR, BGRA or grayscale images with 8 bits per channel.

This plugin is built if `WITH_TGAIMPORTER` is enabled when building Magnum. To
use dynamic plugin, you need to load `TgaImporter` plugin from
`MAGNUM_PLUGINS_IMPORTER_DIR`. To use static plugin or use this as a dependency
of another plugin, you need to request `TgaImporter` component of `Magnum`
package in CMake and link to `${MAGNUM_TGAIMPORTER_LIBRARIES}`. See
@ref building, @ref cmake and @ref plugins for more information.

The images are imported with @ref ColorType::UnsignedByte and @ref ColorFormat::BGR,
@ref ColorFormat::BGRA or @ref ColorFormat::Red, respectively. Grayscale images
require extension @extension{ARB,texture_rg}.

In OpenGL ES BGR and BGRA images are converted to @ref ColorFormat::RGB
and @ref ColorFormat::RGBA. In OpenGL ES 2.0, if @es_extension{EXT,texture_rg}
is not supported, grayscale images use @ref ColorFormat::Luminance instead of
@ref ColorFormat::Red.
