I will enjoy to see a colour/image module in phobos a day.
There is some filters very usefull that are almost unknow like the 
per-multiplied alpha bleeding need to be democratized to improve GUI 
rendering quality.
There is so much issues on images data when rendering on GPU that have 
common fix make me think phobos is a great place for such modules.
