feat(draw): hand one drawn area or line back to the application

createApplicationTools returns drawShape({ shape, signal }): it opens Draw
for one area or line and resolves with its Polygon or LineString without
placing a mark, or null when draw mode is left, the signal aborts, a newer
request replaces it, the pointer is held elsewhere or the tool goes. The
shape controls cannot change the asked-for shape, and a shape across the
antimeridian is refused as a row's actions refuse it and drawn again. It
also returns pointerFree, so an application's own click handlers yield to a
tool holding the pointer, as the layers' do.

 ## [Unreleased]
 
+- Applications can ask Draw for one area or line and get its geometry back
+  without placing a mark (`drawShape` from `createApplicationTools`), and their
+  own click handlers can yield while a tool holds the pointer, as the layers'
+  do (`pointerFree`) (samehkhamis).
