[beta] Cherry pick fix GTK redraw call being called from non-GTK thread (#173667) 
Cherry pick of https://github.com/flutter/flutter/pull/173602

Impacted users: All Linux users of Flutter
Impact Description: Due to calling gtk_window_redraw on a Flutter thread a lock up may occur. The Flutter app will then become unresponsive.
Workaround: No workaround
Risk: Low - fix is to run the GTK call on the GTK thread which is what the correct behaviour should be.
Test coverage: Rendering covered by existing tests, use of thread not explicitly tested, but https://github.com/flutter/flutter/issues/173660 opened to add this in future.
Validation Steps: Run test program in https://github.com/flutter/flutter/issues/173447 which generates many frames and maximizes the chance of a lock up.

Flutter Engine

Setting up the Engine development environment

See here

gclient bootstrap

Flutter engine uses gclient to manage dependencies.

If you've already cloned the flutter repository:

  1. Copy one of the engine/scripts/*.gclient to the root folder as .gclient:
    1. Googlers: copy rbe.gclient to enable faster builds with RBE
    2. Everyone else: copy standard.gclient
  2. run gclient sync from the root folder
