previous fast track logic is useless,
it actually doesn't helpful for performance, just increase the code complexity.

if the transform scale factor for x/y is not identical,
it keeps its both xy scale factor then apply them
for stroking calculation.

Basically, stroke width size is linear,
engine couldn't apply scale factor from the matrix which contains 2 dimensional values.
Thus, we can apply it if the scale factor of x/y is identical.
Otherwise, we should transform every stroke points in the stroking process.
That scenario can be improved with another patch.

sw_engine simulates floating point by integer bit shifting,
it loses the accuracy while converting the number data.
This occurs the inacculated curve points result if it scales up very large size.
So we transform points before converting data in order to avoid losing the numbers less decimal point.

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

if a scene loads a vector resource, it must have viewbox info from the design,
That viewbox will be used as bounding box so that user can scale up/down
the scene by its requirements.

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.

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.

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.
