[Pharo-users] Learning Morphic

I am primarily interested in graphical shapes and bit maps (for fractals). I want to put graphical shapes or bitmaps in a window or bordered area. I have not been very successful in finding documentation about how to do this in Morphic. In contrast, I find the documentation for Roassal easy to find and to the point. Perhaps someone could point me to Morphic documentation (or supply examples) on my area of interest that includes a lot of examples. Thanks.
