v0.10.0

.gtui format 9 (reads v1..v9). Crate 0.10.0.

Added

• Right-drag pans like middle drag or Ctrl + left drag, and a right click opens the action menu
  when the button is released: a right press is ambiguous, so nothing happens until it moves. Under
  two cells of movement it counts as a click and the menu opens at the pressed cell; two cells or
  more pans the view and no menu appears (even if you drag back to where you started). With a menu
  already open a right press still only cancels it.

Changed

• The style menu (s / right click) remembers its stack per kind (box, edge, colour): every
  level you walked through, and the item you stood on in each. Opening it again goes straight back
  down the same path with the cursor on the item you picked, and h walks back to the exact item
  you came from instead of resetting to the first one. So changing a colour twice is s, l,
  Enter. The edit text… entry is gone from the box menu (use i / t); delete stays as the
  last item.
