/**
@brief Compile-time information about OpenGL extensions

Each extension is a @cpp struct @ce named hierarchically by prefix, vendor and
extension name taken from list at @ref opengl-support, for example
`GL::Extensions::ARB::texture_storage`. Note that desktop extensions are
available only on desktop build, OpenGL ES 2.0 extensions which are part of ES
3.0 are available only on @ref MAGNUM_TARGET_GLES2 "OpenGL ES 2.0 build",
vendor OpenGL ES extensions are available only on
@ref MAGNUM_TARGET_GLES "OpenGL ES builds" and WebGL extensions are available
only on @ref MAGNUM_TARGET_WEBGL "WebGL builds".

Each struct has the same public methods as the @ref Extension class
(@ref Extension::requiredVersion() "requiredVersion()",
@ref Extension::coreVersion() "coreVersion()" and @ref Extension::string() "string()"),
but these structs are better suited for compile-time decisions rather than
@ref Extension instances. See @ref Context::isExtensionSupported() for example
usage.

This library is built if `WITH_GL` is enabled when building Magnum. To use this
library with CMake, you need to request the `GL` component of the `Magnum`
package and link to the `Magnum::GL` target:

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

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

See @ref building, @ref cmake and @ref opengl for more information.
@see @ref MAGNUM_ASSERT_GL_EXTENSION_SUPPORTED()
