Stylo

--------------------

Added
^^^^^

- New Domain class, it is responsible for generating the grids of numbers
passed to Drawables when they are mapped onto Images. It replaces most of the
old decorators.
- Drawables are now classes! Any drawable is now a class that inherits from
Drawable, it brings back much of the old Puppet functionality with some
improvements.
- More tests!

Changed
^^^^^^^

- ANDing Images (a & b) has been reimplemented so that it hopefully makes more
sense. The alpha value of b is used to scale the color values of a.
- Along with the new Domain system mapping Drawables onto Images has been
reworked to hopefully make coordinate calculations faster

Removed
^^^^^^^

- stylo/coords.py has been deleted, this means the following functions and
decorators no longer exist
+ mk_domain - Domains are now a class
+ cartesian (now built into the new Domain object)
+ polar (now built into the new Domain object)
+ extend_periocally (now the .repeat() method on the new Domain object)
+ translate (now the .transform() method on the new Domain object)
+ reflect (not yet implemented in the new system)

-------------------

Added
^^^^^

- Image objects can now be added together, this is simply the sum of the color
values at each pixel
- Image objects can now be subtracted, which is simply the difference of the
colour values at each pixel

Changed
^^^^^^^

- Renamed hex_to_rgb to hexcolor. It now also can cope with rgb and rgba
arguments, with the ability to promote rgb to rgba colors

-------------------

Added
^^^^^

- Keyword argument 'only' to the 'polar' decorator which allows you to ignore
the x and y variables if you dont need them

Fixed
^^^^^

- Forgot to expose the objects from interpolate.py to the top level stylo
import
- Examples in the documentation and enabled doctests for them

-------------------

Fixed
^^^^^
- Stylo should now also work on python 3.5

Removed
^^^^^^^
- Deleted stylo/motion.py as its something better suited to a plugin
- Deleted Pupptet, PuppetMaster and supporting functions as they are broken and
better to be rewritten from scratch

-------------------

Added
^^^^^

- Sampler object which forms the basis of the new Driver implementations
- Channel object which can manage many Sampler-like objects to form a
single 'track' of animation data
- A very simple Driver object which allows you to collect multiple Channel
objects into a single place
- linear, quad_ease_in, quad_ease_out interpolation functions

Docs
""""

- Added the following reference pages
+ Image
+ Drawable
+ Primitive
+ Sampler
- A How-To section
- How-To invert the colours of an Image

Changed
^^^^^^^
- Image.__and__() now uses a new method which produces better results with
colour images

Fixed
^^^^^
- Numpy shape error in Image.__neg__()

Removed
^^^^^^^
- stylo.prims.thicken was redundant so it has been removed

-------------------
