@brief Format of pixel data

Note that some formats can be used only for framebuffer reading (using
@ref AbstractFramebuffer::read()) and some only for texture data (using
@ref Texture::setSubImage() and others), the limitations are mentioned in
documentation of each particular value.

In most cases you may want to use @ref PixelFormat::Red (for grayscale images),
@ref PixelFormat::RGB or @ref PixelFormat::RGBA along with
@ref PixelType::UnsignedByte, the matching texture format is then
@ref TextureFormat::R8, @ref TextureFormat::RGB8 or @ref TextureFormat::RGBA8.
See documentation of these values for possible limitations when using OpenGL ES
2.0 or WebGL.
