2123899cc6 Jank insted of flicker in Mozart 
Currently there's no good way of synchronizing layout changes with children in

Mozart. Previously we flickered when we were out of sync with our child. Now we

jank instead because that's a more acceptable artifact while we work on

improving Mozart.

3f7d5ef6f8 Update code to account for Mozart changes 
The layout protocol in Mozart changed. Now we need to pipe a scene version
through the system to the compositor.

e3c3be1c21 Handle 0x0 sizes in Mozart 
When we're created off-screen, Mozart gives us a 0x0 view to populate. Rather
than trying to draw a 0x0 texture, we just acknolwedge the frame request
immediately. This matches what we do in the non-Mozart rasterizer.

e416866484 Enable Mozart hit testing 
We now mark our root node as opaque to hit testing. We don't seem to be getting
events in child views, however.

d3dbc1cda4 Polish Mojo platform implementation 
* Use Node::Combinator::PRUNE, which stops the Mozart launcher from showing red
  when we're loading child views. Instead of blocking the whole app, we'll now
  just prune away the children that aren't ready. Eventually we'll want
  to let authors control these operations.

* Grab the service registry in AcceptConnection rather than CreateView. The
  CreateView comes from the Mozart launcher, which isn't where we want to get
  the service registry. Now we get the service registry from the first app to
  connect, which isn't right either but at least works while we sort out what
  we really want.

4b921cbb5e Make Mozart draw child views 
Previously we weren't factoring in the layer's offset properly and we were
drawing the child views below the background layer.

e3bf0fa3c1 Include child scenes when uploading to Mozart 
Previously we just dropped child scenes on the floor. Now we upload them
to Mozart. However, we just draw them on top of all the other content
and don't apply any clips or blends.

052d65cc14 Clear the Flow raster cache when a GrContext is destroyed 
After an application is suspended and the GrContext associated with the
Flutter view is destroyed, the raster cache still contains images tied
to the defunct context.  The SkyShell process will crash if these images
are used after the application resumes.

6d1af600b1 Trim unneeded depedendencies from sky/compositor 
Now we just depend on Skia and Base, which makes the compositor easier
to understand.

Also, update our skia/ext/refptr.h to match the current version of the
code in Chromium. This version adds support for several useful C++11
patterns.

795df1327b Plumb physical size along with SkPicture 
Previously we were using the cull rect of the SkPicture to size the GPU buffer,
but Skia is too smart and shrinkwraps the cull rect, which meant we weren't
sizing the GPU buffer to the right size.
