    `NoCreate constructors`_
    ========================

    .. TODO: link to NoCreate once m.dox handles variables properly

    Compared to C++, the Python APIs don't have an alternative to the
    :dox:`NoCreate <NoCreateT>` constructor tag. In C++ these make it possible
    to have class members initialized before a GL context is present, but in
    Python there's no such limitation so these don't make sense.

    `Buffer ownership and reference counting`_
    ==========================================

    Unlike in C++, where a :dox:`GL::Buffer` is either :dox:`std::move()`\ d
    into the mesh or referenced externally (with the user being responsible for
    its lifetime), the `gl.Mesh` object keeps references to all buffers added
    to it.

.. py:property:: magnum.gl.Mesh.primitive

    While querying this property will always give back a `gl.MeshPrimitive`,
    this property can be set using either `magnum.MeshPrimitive` or
    `gl.MeshPrimitive`, similarly to how the overloaded
    :dox:`GL::Mesh::setPrimitive()` works.

.. py:property:: magnum.gl.Texture1D.minification_filter

    See `Texture2D.minification_filter` for more information.

.. py:property:: magnum.gl.Texture2D.minification_filter

    This property accepts either a tuple of `magnum.SamplerFilter` /
    `gl.SamplerFilter` and `magnum.SamplerMipmap` / `gl.SamplerMipmap` values
    or just `magnum.SamplerFilter` / `gl.SamplerFilter` alone in which case
    `gl.SamplerMipmap.BASE` will be used implicitly; similarly to how the
    overloaded :dox:`GL::Texture::setMinificationFilter()` works.

.. py:property:: magnum.gl.Texture3D.minification_filter

    See `Texture2D.minification_filter` for more information.

.. py:property:: magnum.gl.Texture1D.magnification_filter

.. py:property:: magnum.gl.Texture2D.magnification_filter

    This property accepts either `magnum.SamplerFilter` or `gl.SamplerFilter`,
    similarly to how the overloaded :dox:`GL::Texture::setMagnificationFilter()`
    works.
