Describe the issue

There appears to be an “out of sync”(?) problem with code examples in the Customized visualization tutorial which may exist in other parts of the doc. The problem is in both the released and latest versions of the tutorial. The code box under Mimic draw_geometries() with Visualizer class shows:

37
38
39    def custom_draw_geometry_with_rotation(pcd):
40
41        def rotate_view(vis):
42            ctr = vis.get_view_control()
43            ctr.rotate(10.0, 0.0)
44            return False

Which appears to show a window (lines 37-44) into: customized_visualization.py in the master/latest source code. But in that Python file, this function (custom_draw_geometry_with_rotation()) actually spans lines 39-47. So a key bit of the function:

          o3d.visualization.draw_geometries_with_animation_callback([pcd],
                                                                    rotate_view)

is not shown in the tutorial.

Hello, I am working on this on my fork

[cwreynolds]

Thanks @dancergraham! I appreciate you looking into this.

I hope eventually to know enough about Open3D to submit my own pull requests. Right now I'm too much of a noob.

Well you're definitely on the right track - your detailed issue notes made it fantastically easy for me to submit my first PR here on the repo!
