To make a BitmapData copy of your vector(drawing API generated) canvas using the draw() method every now would need a slightly different approach:
You would have a bitmapData made by drawing 2 bitmaps.

GDI+ is definitely the way to go draw with the lib....
To draw lines, polygons, rectangles etc., don't you?
Can you explain what abstraction you would want complicated drawing and animation in XAML alone.

I think you can do GDI+ drawing in just about any window in a .net windows forms project, but what do you recommend as the best built-in control for containing custom drawing? I'm going to be drawing my own x-y plots, text and images. I could use a Panel...

Try putting your drawing code on a timer....
Of such views in layers, all with lots of fancy CG stuff (drawing and filling paths, clipping images: is effectively synchronous, so expensive drawing operations can kill a loop's performance.
