clients: Add color
Add a client that creates a surface with one color using single pixel buffer. Set to that surface an image_description created with the parametric creator of the color management protocol. This client can get as params: 1. Width and height 2. Color channels R, G, B, A 3. The name of primaries 4. The name of a transfer function 5. The min, max, ref luminance levels Signed-off-by: Joan Torres <joan.torres@suse.com>
