      New issue 1337: annotate_scale does not work for non-unity aspect ratio

Hsi-Yu Schive:

The annotate_scale() function does not work when the aspect ratio is not unity.

Example code:
```
#!python
import yt
from yt.units import kpc
ds = yt.load("IsolatedGalaxy/galaxy0030/galaxy0030")
slc = yt.SlicePlot(ds, 'z', 'density', center=[0.5, 0.5, 0.5],
                   width=(15*kpc,20*kpc))
slc.annotate_scale(coeff=2.0, unit='kpc', pos=(0.1,0.1))
slc.save()
```

The code works fine when changing the width to (20\*kpc,20\*kpc).
