Bug 1366097 - Part 4. Mark VectorImage as surface as shared when used outside an image layer. r=tnikkel This is important because it ensures we release the shared memory handle (although not the data itself) for the underlying surface buffer when it turns out we will probably never need to share it. If we do need to share the surface data with the GPU process, it will reallocate a handle if necessary, and close it when it is finished. On some platforms we only have a finite number of handles, so if we don't need them, we should close them.
