ShapeNode -> Shape
SceneNode -> Scene
We can keep clean and neat shorter names.

Also, added one more showcase how to update only necessary properties of a shape
while retaining other properties...

Obivously, we need to clear target before drawing.
Thus canvas request to renderers to clear buffer.
the implementation is upto backend engines.

These interfaces might not perfect optmizied,
but you can build path commands easier than manual data set.

it's usage may require a little handy but
The path data is very low manipulated, its usage may require a little handy,
but appedingPath() is designed for performance.
Also added testPath.

This allocates nodes slots in advance to avoid memory grow & copy.
it will be benefit if you know how many shapes will be used in your canvas.

introduce Canvas class to replace the CanvasBase.
now, SwCanvas, GlCanvas inherits this Canvas for polymorphism
and remove duplicated interfaces.

To show the result, we use efl library.
Most linux distribution supports efl library from their package repo,
you can easily install efl from its package repo:
Ubuntu:
$ apt-get install libelementary-dev
Or, please visit efl site to install EFL libarary manually:

Adjust rle span generation size to reduce memory allocation.
This span growing is experimentally increased, undeterministic.
Thus We need too increase them every requests, if we increase their
size x 4, we can avoid a lot of memory copy in advance.

Introduce project skeleton such as build envrionment and interfaces
to build up code further cooperatively.
