Merge commit '52780b336a46654163e0d34204a0aad0da5fdf33'

Move the authoritative 'point' out of the pane and into the doc_data.

This seems a more sensible location.
The point still exists in the pane as it is very useful, but this is
now just a 'borrowed' pointer.

This required changing doc_attr to only examine a single pane.
