the programmer only moves, resizes, shows, hides etc. the objects that they
need to change. The programmer simply thinks at the object logic level, and
the canvas software does the rest of the work for them, figuring out what
actually changed in the canvas since it was lastdrawn, how to most
actually changed in the canvas since it was last drawn, how to most
efficiently redraw he canvas and its contents to reflect the current state,
and then it can go off and do the actual drawing of the canvas.
This lets the programmer think in a more natural way when dealing with a
display, and saves time and effort of woring out how to load and display

images, render given the current display system etc. Since Evas also is
portable across different display systems, this also gives the programmer
