Perform OpenGL compositing in the Flutter thread and write to a framebuffer. (#172090) 
This framebuffer then gets copied into GTK during the draw calls. This
disconnects the Flutter rendering from the GTK rendering which will
allow us to render Flutter using EGL directly and support rendering
without any views present (required for multi-window).

Framebuffers are shared between the Flutter and GTK OpenGL contexts
using EGLImage. When running under X11 GTK uses GLX and this is not
possible - instead the buffers are copied via the CPU in this case.

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
