A few changes are necessary to allow fetching textures provided by
the render processes through IPC and bound to their respective GL
context in the GPU process and use them in the QtQuick scene graph.
- Remove the plain color test textures.
- Allow setting the QtQuick QOpenGLContext's handle as the share
context for all context set as shared in the Chromium GPU process.
We do this by letting the GpuChannelManager ask us for a
ShareGroup instance responsible for returning a sharing GL context
handle.
- Fetch texture IDs from the MailboxManager used by the GPU process
using the Mailbox given to us in the DelegatedFrameData.
This is the same mechanism used by Chromium to share textures
between "client" GL contexts.
- Keep the QtQuick scene graph threads and Chromium in-process GPU
thread separate. The complicated part of merging those two
rendering pipelines on the same thread is that it would force Qt
to also use only one thread for rendering. For the moment we will
try to synchronize those threads together instead.
- Lock the Qt SG thread while waiting for resource sync points.
Do so by posting a callback to the Chromium GPU thread and wait
until the sync point of every resource has been retired by the
producing contexts.
- Acknowledge the delegated from once QtQuick swapped the GL buffers
instead of right after we added the frame to the scene graph.
This fixes some issues where the textures for the previous frame
would already be released as Chromium was producing the new frame.
There are still a few issues regarding synchronization that have to
be fixed, especially when Qt triggers the rendering of a new frame
while Chromium is starting to produce the next frame.
Note: To enable it we still need to pass the following command switches:
--enable-delegated-renderer --enable-threaded-compositing --in-process-gpu

This allows the Chromium GL code to initialize on the display created
by Qt.

This is necessary because I pushed patches
on top of the 3rdparty submodule to debug
the mac CI bot.

This provides a stub implementation that renders quads and RenderPasses
using QSGNodes in QQuickWebEngineView.
The BackingStore code path is still supported when the delegated renderer
switch is not enabled. To use the new rendering, pass the following switches:
--enable-delegated-renderer --enable-threaded-compositing
This uses debug, plain color textures until we can fetch tiles and
textures from the ResourceProvider across OpenGL context boundaries.

The new 3rdparty submodule contains snapshots of both ninja
and chromium. This drastically reduces the size of the repository
and can be used by our CI system.
