Comment (by petr@…):

 For `py-matplotlib` there seems to be no strict requirement for PIL
 neither. Import are found only in `lib/matplotlib/backend_bases.py`,
 `lib/matplotlib/image.py` and `lib/matplotlib/tests/test_image.py`, but
 the absence of PIL is handled smoothly. All other occurrences are only in
 documentation or examples.

 So the missing dependence on PIL seems to be intentional.

 From `lib/matplotlib/backend_bases.py`:
 {{{
 try:
     from PIL import Image
     _has_pil = True
 except ImportError:
     _has_pil = False

 _backend_d = {}
 }}}

 From `lib/matplotlib/image.py`
 {{{
     def pilread(fname):
         """try to load the image with PIL or return None"""
         try:
             from PIL import Image
         except ImportError:
             return None
 }}}

 From `lib/matplotlib/tests/test_image.py`:
 {{{
 try:
     from PIL import Image
     HAS_PIL = True
 except ImportError:
     HAS_PIL = False
 }}}
