Yeah, I just made it very colorful mostly to prove the point that we
have very granular control.  I think Randys patch was very good, because
imo _most_ of the noise is the bracket/pointer/operators etc.

Sure!

Yep, I agree!  Go ahead :-)

stuff like:
```
 add_edge:  // <- this thing
  gx += WINDOW_LEFT_EDGE_X (w);
  gy += WINDOW_TOP_EDGE_Y (w);

 store_rect: // <- and this thing
  STORE_NATIVE_RECT (*rect, gx, gy, width, height);

```

I think you should just tweak it like you want.  I think it's very
time-consuming creating separate patches and bug-reports for small
tweaks and maintenance issues.  I trust your judgment here, though I
also think that Randy had some nice ideas :)

Just hack away!
