The opacity attribute controls the opacity of the canvas and its
children. Be careful, it's a cumulative attribute: the value is
multiplied to the current global opacity, and the result is applied to
the current context color.
For example: if your parent have an opacity of 0.5, and one children have an
opacity of 0.2, the real opacity of the children will be 0.5 * 0.2 = 0.1.
Then, the opacity is applied on the shader as::
frag_color = color * vec4(1.0, 1.0, 1.0, opacity);
