squawk 0.1.3

• The report sheet is two steps. First the screenshot fills the screen at
  its real size, with only a slim bar of tools at each end, so a finger
  has the whole screen to aim at. Then Next slides the form up over the
  drawing for the description and the email. Before, the form sat under
  the screenshot and took what height it needed, which left the picture
  at about half size and shrank it to a thumbnail when the keyboard came
  up.
• Two fingers pinch to zoom in, up to four times, and drag to pan. A Fit
  button brings the whole picture back. A second finger landing mid-stroke
  cancels that stroke instead of leaving a dot.
• The keyboard pushes the sheet and never the drawing. The sheet follows
  a drag from its grab bar and goes past a third of the way down or on a
  flick. Tapping the drawing or the Android back button returns to the
  drawing too, with the typed text kept.
• The example's dev harness has a System / Light / Dark switch, so the
  sheet can be checked against every theme mode.
• Nothing changes in what is sent: drawings were always stored in
  screenshot pixels and still are.
