Enum ParamType

pub enum ParamType {
    Float(f32),
    Float2([f32; 2]),
    Float3(Box<[f32; 3]>),
    Float4(Box<[f32; 4]>),
    Surface(Box<Surface>),
    Sampler2D(Box<Sampler2D>),
    Other(Box<Element>),
}

A parameter’s type. We do not have full support here, but unknown types can be retrieved in the Other variant.
