I might have been wrong about CPicture. The Bitmap-class used to store
all images except icons today has GetPixel()/SetPixel()-methods. Those
could be exposed from CPicture and utilized.
In conjunction with a way to create a CPicture instance containing a
blank image of given dimensions everything needed is in place.
(Efficient enough? Don't know. Time will tell...)
