 * The result then looks exactly like above diagram, without adding any extra dependency
    to Moz2D.
+What we ended up doing:
+Instead of directly referencing the GLContext, the GrContext only references the
+DrawTargetSkia referencing it. In this way, the only raw pointer we have is just
+walking back a strong reference. As planned, DrawTargetSkia references the GLContext
+by means of a virtual base class, so no dependency is added to Moz2D.
