[cairo] how to draw on OSX

I've asked a question kind of like this before, but this time, I've
made sure I have a newer version (1.4.2). I'm doing the following
sequence (in pseudocode):
nsGC = [NSGraphicsContext graphicsContextWithWindow: anNSWindow];
cgRef = [nsGC graphicsPort];
surface = cairo_quartz_surface_create_for_cg_context(cgRef, 300, 300);
cr = cairo_create(surface);
cairo_set_source_rgb(cr, 0.0, 0.0, 1.0);
Is this the sequence other's use for drawing on quartz windows?
Because it doesn't update. If I drag the window, it seems to flush
the GC. Do I have to follow every cairo paint() call with some sort
of sync to the quartz APIs? Or is there a flag I can set that will
make it happen right away?
Time and Countertops. They both get used up way too fast.
