v7.0.2

Component

• Bugfix: Fix high CPU usage (app and terminal emulator, e.g. tmux) caused by a
  cursor position request/reply feedback loop redrawing the screen at ~60fps in
  the non-alternate-screen modes. See #1302.
• Animation frames are now produced only when requested via
  animation::RequestAnimationFrame() (e.g. by animation::Animator), as in
  FTXUI 6. Receiving an event no longer implicitly triggers an animation
  frame.
• Bugfix: App::PostEvent is now thread safe again, as documented. Since the
  7.0.0 event loop rework it pushed into an unsynchronized buffer, racing with
  the main loop when called from another thread.
• Bugfix: Fix unbounded memory growth in the event buffer. A receiver used
  during terminal setup was kept for the whole App lifetime, retaining every
  subsequent event (including every mouse move).

Dom

• Performance: text computes its requirement once and renders only the
  visible lines. This makes scrolling a large text inside a frame
  significantly faster. Thanks @patlefort. See #1309.
• Performance: text selection now only visits and stores the selected line
  range, instead of scanning and allocating one entry per line of the whole
  text on every frame.
