// size and we implement a SkPixelRef in order that Skia can write directly to

|
// the pixel memory backing the Pixbuf.
|

|
|
// We then provide an accessor for getting the pixbuf object and that can be

|
// drawn to a GDK drawing area to display the rendering result.

|

// This is all quite ok for test_shell. In the future we will want to use
|

// shared memory between the renderer and the main process at least. In this
|
|
// case we'll probably create the pixbuf from a precreated region of memory.
