sticky scroll for treeviews

[cognominal]

aticky scroll has become an invaluable way to understand the place of the current syntactical construct in the source hierarchy in the current editor.

I miss it a lot in the explorer tree view for deep workspaces like vscode itself. There are some treadoffs. If the treeview is not high enough, the sticky part would take too much place. With a large enough treeview, the view could bundle dirs.

Suppose the two first lines are sticky :

+ dir
+ | subdir
    file1

could be represented giving place for another file in the non sticky part

+ dir / subdir
  file1
  file2

If more lines are taken by the sticky parts than the non sticky one. Stickiness should be ignored.
