Hi, I have a question about using named interface blocks in Glium.

What I mean by that is GLSL syntax like this:

layout(std140) uniform Light {
  vec3 position
} light;

out vec4 color;

void main() {
  color = vec4(light.position, 1.0);
}

On the Rust side, I created a struct like:

#[repr(C)]
#[derive(Copy, Clone, Debug)]
pub struct Light {
    pub position: [f32; 3],
    // Not sure if needed
    _padding0: i32,
}
implement_uniform_block!(Light, position);

And I tried calling draw with uniform! { light: Light {...} } and uniform! { Light: Light {...} }, without success:

• The first one doesn't do anything (values in GLSL are all 0s)
• The second one errors with UniformBlockLayoutMismatch { name: "Light", err: MissingField { name: "Light" } }

Does Glium support? If so, how do I use this correctly? Thanks!
