Complex Plotting App

Of course, if we turn the contour grids off in the plot option the plot time comes down to 3:17 for the same graph, so if we find some way to optimize drawing the contour grid I think we can reduce the time further.

Also, I found an interesting complex graph implementation done in javascript here:

The source shows a lot of optimizations for drawing complex graph that could be beneficial in optimizing our code here, as well as some other feature implementations such as doing conformal mapping based on image (world map), and interactive animation support (similar to HP Prime's Geometry app).

I'm testing out an idea which is based on the other link you provided.

The idea is to store the result F evaluated at specified rows and columns and then use LINE_P at the end. The result is (hopefully) similar to what you see in section 0.1 (see link). It's an alternate method for generating the contours, but rather than generating the entire set of contours, it would simply show the map of the original z plane limited to Xmin/Xmax and Ymin/Ymax under the function f. That way, we also get a better idea of how the map affects the rectangular plane as a whole.
