Creates a gsk.render_node.RenderNode that will drawn the child with color_matrix.
In particular, the node will transform colors by applying
pixel = transpose(color_matrix) * pixel + color_offset
for every pixel. The transformation operates on unpremultiplied colors, with color components ordered R, G, B, A.
