pub struct UiButton {
    pub label: String,
    pub position: Vec3,
    pub normal_color: Vec4,
    pub hover_color: Vec4,
    pub press_color: Vec4,
    pub border_color: Vec4,

    /* private fields */
}

A clickable text button.

Tracks hover (via NDC mouse position) and click state. Triggers on_click callback when the left mouse button is released over it.
