01b550497c sw_engine: support stroke transformation properly.
also updated transform test cases.

Yet, this engine is not well optimized,
If they are too mch sluggish,
you can use ELM_FPS envrionment lowing down the fps
when you launch test cases...

ex) $ELM_FPS=30 ./testSceneTransform

you can test with testStroke example

a5f15a588c common scene: complete scene tranfsormation feature.
Each scene could conserve its own transformation,
the origin could be the parent Paint (if they were beloned to)

Thus, you can compose the multi-tranformed scene group which
simultenoulsly working in own spaces.

See testTransform and testSceneTransform, how they work.

b08d144dc9 common shape: introduce transformation matrix
Paint supports translate, rotate, scale functions for transformation

The origin of these transformation is center of the paint,
thus you have to consider the center-aligned vertices if you'd like to use
these transformation functions.

This policy has been considered for scene transformation.

682bc25298 common shape: revise scale/rotate approach.
Come to think of it, this optimized method is not so useful,
it could just bring the user misunderstanding and
not to efficient as I expected in the most cases.

So, changed policy for transformation behaviors.
it keeps the properties as others but leaves it to the backend implementation.

Plus, this change contains the correct RenderUpdateFlag.
You can refer the flag in the backend to figure out which kinds of properites has been updated

42c56757df common: redesigned interfaces
PaintNode -> Paint
ShapeNode -> Shape
SceneNode -> Scene

We can keep clean and neat shorter names.
