canvas map: introduce a new texture mapping for better quality.

Summary:
This new implementation of evas map texture mapping
 is designed for high quality rendering same level to GL.

If you use a high-end device, performance is not too bad, you can turn this on.
You might have practical image quality even in software rendering.

Since this implementation still have a few optimization points (+simd)
and stablizings, it may be useful in somewhat limited envrionments right now.
However the functionality definitely works fine, so please turn this on by
demand (anti_alias + smooth) for a while.
