previous implementation didn't consider multiple canvases,
multiple canvas shared one renderer engine that brought corrupted contexts.
Thus, each canvas instances should have designated renderer engine instances.
Now fixed.
initialization interfaces has been changed for threads count.
if you want to set concrete threads count by system, please specify thread count with it.
std threads:
tvg::Initializer::init(tvg::CanvasEngine::Sw, std:🧵:hardware_concurrency());
if your system provides designed threads info, you can use it.
efl:
tvg_engine_init(TVG_ENGINE_SW, eina_cpu_count());
I recommend to avoid max threads usage for better performance.

We can use RGBA colorspace rather ARGB for pixel data.
This would be better for many rendering system,
since it's more widely preferred than ARGB including opengl.

picture now affords the memory data as input source so that
user can pass svg data memory directly.

Some user have no idea of premultiplied alpha concept,
We suggest more user-friendly interfaces so that they don't confuse it.
Now, this pre-multipying is acommplished by backend engines.

1. removed async option which doesn't work currently,
rather than it, we can add async option in initiailizer class.
2. removed update() method.
Instead, we can call update(paint = nullptr); which has exactly same behavior.

avx is the cutting edge method for intel & amd cpus simd instruction.
We are going to support this feature for the desktop environment (instead of sse)
You can turn on this with configuration something like this:
$meson . build -Dvectors=avx
Current patch supports only for raster solid color

we don't need to apply anti-aliasing if stroke is there.
here turns off anti-alias if stroke width is more than 2.
magic number 2 is experimentally confirmed.

if the rectangle is not transformed, we don't need to use rle method.
we can directly raster pixels onto the bounding box.

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

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