this matrix data is volatile since it's coming from stack memory.
thus engine should record its own memory space for keeping it.

there are a logical wrong that memory increase size,
it correct that also tune the number to reduce memory allocation time.
Now scene transform test works smoothly.

there are unnecessary partial spans generated in orthogonal rectangle.
we can merge those partial spans to others if they are on the same scanline...

memset() is more than 10x faster than manual loop.
Thus we replace it to manipulate buffer pixels.

this bounding box max indicates absolute positions,
not width/height size.
because of this, shape couldn't rendered properly,
when it's clipped out.

this interface is designed for user-defined arbitrary affine-transform paints.
required by svg loader.

replace dynamic_cast to static_cast,
This can be a controversial choice between optmization and clean code.
Obviously we know the converting types,
try avoiding a bit heavier casting some cases.

We prefer to build up a tiny compact engine at memory rather than compatibility,
this engine is not considerd for end-users but designed for middle-level framework
and some low-level users.
Thus, we won't consider 64bits data size,
use explicit 32 bits data until coming next upgrade...

Introduce Result type for notifying caller more detailed info.
We should implement the result values for each apis, with practical values.

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

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.
