danakj, could you verify the correctness of this -- IIRC you mentioned a need to
do something to handle this case before I left, but now I forget what the
details were.

[hubbe, 2016/09/02 21:35:49]

Acknowledged.

-  PerCompositorDataMap::iterator it = per_compositor_data_.find(compositor);
-  if (it == per_compositor_data_.end())
-    return;
-  PerCompositorData* data = it->second.get();
+  PerCompositorData* data = per_compositor_data_[compositor].get();
+  if (!data)
+    data = CreatePerCompositorData(compositor);

I don't think you want to do this. Instead just store it in the ui::Compositor
and set it on the GPTF when you make a new output surface. Take a look at how
visible is done.

[hubbe, 2016/09/02 21:35:49]

Added it to ui:Compositor.
Does that mean we don't need PerCompositorData::color_space anymore?

[danakj, 2016/09/02 21:36:47]

Ya that'd be ideal.

[hubbe, 2016/09/02 22:30:47]

Gone.

   DCHECK(data);
   data->color_space = color_space;
   if (data->display)
