Imageio

The ffmpeg plugin has been refactored:

* The core has been moved to a new library: imageio-ffmpeg.
* That library provides platform-specific wheels that includes ffmpeg,
so just ``pip install imageio-ffmpeg`` instead of the download step.
* Note that this new library is py3k only.
* Termination of ffmpeg subprocess is now more reliable.
* The reader of the ffmpeg plugin now always reports ``inf`` as the number of
frames. Use ``reader.count_frames()`` to get the actual number, or estimate
it from the fps and duration in the meta data.
* Removed ``CannotReadFrameError``.

Other changes:

* The avbin plugin has been depreacted and will be removed in a future version.
* Imnproved speed for PIL and FFMPEG plugsins by avoiding memory copies.
* Update the included tiffile library.
* Support for SimpleITK.
* Speed up tiffile plugin when writing to something else than a filename.
* Fix that writing to a file object would not work for some plugins.
* Can now pass image data to the write functions as anything that resolves to
a numpy array with a numeric dtype.
* One can now read from a memoryview.
* Fix error related to paletted BMP with the Pillow plugin.
* Improved logging.

* Fix installation issue on flavors of Ubuntu 14.04 /w Python 2.7 (378).
* Use `np.frombuffer` instead of `np.fromstring` in some cases.

* Renamed ``Image`` class to ``Array`` and add documentation for this ndarray subclass.
* Reading from HTTP and zipfiles has been improved and better documented.
* Improvements to reading and writing of Tiff metadata (by Lukas Schrangl).
* Better dealing of tifffile dependencies on Python 2.7 (330 and 337 by Chris Barnes).
* Reader for the SPE format (358 by lschr).
* Better termination of FFMPEG when reading from webcam (346 by Dennis Vang).
* FFMPEG support for reading 16bit videos (342 by Peter Minin).

* Console entry points for binary downloads (by Paul Mueller).
* Dropped support for Python 2.6, 3.2 and 3.3.
* Reading images from a url can now also have "suffixes" like "?query=foo".
* The ``mimwrite()`` and ``mvolwrite()`` functions also work with generators.
* Fix rounding of float data.
* New Lytro plugin (by Maximilian Schambach).
* New plugin based on BSDF format (for images/volumes and series thereof,
including support for random access and streaming).
* TIFFFILE update to latest ``tifffile.py`` implementation.
* DICOM fix that could fail in the presence of a directory.
* PILLOW improvements to API to provide same functionality as Scipy's ``imread()``.
* PILLOW fix for Gamma correction (302).
* PILLOW now allows JPEG images to be read from a url.
* PILLOW fix determining of grayscale in 1 bit paletted images.
* FFMPEG improved device name parsing (by Dennis van Gerwen).
* FFMPEG now allows more control of position of extra parameters.
* FFMPEG improved parsing of fps from ffmpeg info.
* FFMPEG reader allows has ``fps`` argument to force reading at a specific FPS.

* New format for grabbing screenshots (for Windows and OS X).
* New format for grabbing image data from clipboard (Window only).
* Multipage Tiff files can now be read using ``volread()`` to obtain the image
data as one array.
* Updated the ffmpeg executables that imageio provides.
* The ffmpeg format can now also use the ffmpeg exe provided by the ffmpeg
conda package (``conda install ffmpeg -c conda-forge``).
* Fixes to ffmpeg format in general.
* Improve docs and rounding in animated GIF duration.
* Fix for setting number of loops in animated GIF.
* Fixes for transparent images in Pillow.
* Fixes for float indexing that is disallowed in new Numpy (Freeimage plugin).
* Fix for using missing ``close()`` on Pillow images.
* Updated version of tiffile plugin.

A bugfix release:

* Fix animated gif writer that was broken in newer Pillow version.
* FFMPEG plugin improvements: more reliable fps detection, can deal
with missing FPS, more reliable subprocess termination,
* Mimread allows a few missing frames to better deal with certain video files.
* Allow question marks in url's.
* Allow Pillow plugin to read remote files by "enabling" ``seek()`` and ``tell()``.
* Use invoke to run development tasks instead of custom "make" module.
