@section GL-RectangleTexture-usage Usage

Common usage is to fully configure all texture parameters and then set the
data from e.g. @ref Image2D. Example configuration:

@snippet MagnumGL.cpp RectangleTexture-usage

In a shader, the texture is used via @glsl sampler2DRect @ce,
@glsl sampler2DRectShadow @ce, @glsl isampler2DRect @ce or @glsl usampler2DRect @ce.
See @ref AbstractShaderProgram documentation for more information about usage
in shaders.
