How should one draw stuff?
There are a few different things that can be done,
1)Draw lines, polygons, circles etc.
2)Draw letters
3)Draw something (lines, pixels, etc.) and then redraw it at a sligthliy different position (i.e. animation).
4)Load an image from a file and draw it, and possible also move it around as some kind of animation.

I read about the Arthur painting system and look at the tutorials but I can't make a connection between these two. How should these things REALLY be done?
Any ideas?
