+To provide a shim layer over Pillow/PIL situation until the PIL support is
+removed.
+
+
+Combinations To Account For
+===========================
+
+* Pillow:
+
+    * never has ``_imaging`` under any Python
+    * has the ``Image.alpha_composite``, which may aid in detection
+
+* PIL
+
+    * CPython 2.x may have _imaging (& work)
+    * CPython 2.x may *NOT* have _imaging (broken & needs a error message)
+    * CPython 3.x doesn't work
+    * PyPy will *NOT* have _imaging (but works?)
+
+Restated, that looks like:
+
+* If we're on Python 2.x, it could be either Pillow or PIL:
+
+    * If ``import _imaging`` results in ``ImportError``, either they have a
+      working Pillow installation or a broken PIL installation, so we need to
+      detect further:
+
+        * To detect, we first ``import Image``.
+        * If ``Image`` has a ``alpha_composite`` attribute present, only Pillow
+          has this, so we assume it's working.
+        * If ``Image`` DOES NOT have a ``alpha_composite``attribute, it must be
+          PIL & is a broken (likely C compiler-less) install, which we need to
+          warn the user about.
+
+    * If ``import _imaging`` works, it must be PIL & is a working install.
+
+* Python 3.x
+
+    * If ``import Image`` works, it must be Pillow, since PIL isn't Python 3.x
+      compatible.
+
+* PyPy
+
+    * If ``import _imaging`` results in ``ImportError``, it could be either
+      Pillow or PIL, both of which work without it on PyPy, so we're fine.
+
+
+Approach
+========
+
+* Attempt to import ``Image``
+
+    * ``ImportError`` - nothing is installed, toss an exception
+    * Either Pillow or the PIL is installed, so continue detecting
+
+* Attempt to ``hasattr(Image, 'alpha_composite')``
+
+    * If it works, it's Pillow & working
+    * If it fails, we've got a PIL install, continue detecting
+
+        * The only option here is that we're on Python 2.x or PyPy, of which
+          we only care about if we're on CPython.
+        * If we're on CPython, attempt to ``import _imaging``
+
+            * ``ImportError`` - Bad install, toss an exception
