Write the pixels per 64-bit data.
This optimization can potentially double the performance in the best case scenario.
It's visually noticeable, especially when the resolution is sufficiently large.

These new apis would enable users to easily modify the motion scene,
The data structure of the paints has been changed from an array to a list.
@APIs:
std::list<Paint*>& Canvas::paints() noexcept;
std::list<Paint*>& Scene::paints() noexcept;
@Deprecated:
Result Canvas::reserve(uint32_t size) noexcept;
Result Scene::reserve(uint32_t size) noexcept;

Reduce duplicated masking raster code by replacing with c++ templates
this change does not noticeably impact performance (< error bound).
Binary Size diff: 218379 -> 217851 (-0.5kb)
Reduce duplicated image raster code between scaler approaches.
Although this allows for a function call per pixel,
this change does not noticeably impact performance (< error bound).
Binary Size diff: 222541 -> 218379 (-4kb)
Reduce excessive gradient filling code duplication by employing C++ template method.
This change does not affect performance or binary size adversely.
Binary Size Diff: 223399 -> 222693 (-706)
Unify textmap methods that are overly duplicated with each other.
Still trying to simplifying raster code so that thorvg could introduce
the a bunch of masking method code nicely.
This reduces the size like: 214773 -> 212843 (-2kb)
Compact blending instructions by distinquish the
shape & images. since we gurantee the shape color is
premultiplied alpha.
As a result, this enhanced performance by 0.002s in examples/Performance
on my local machine.
This also contains code cleanup chores.

WARNING:: You should add the boolean check kwarg to the run_command call.
It currently defaults to false,
but it will default to true in future releases of meson.

The CompositeMethod now includes the newly supported InvLumaMask option:
The source pixels are converted to grayscale (luma values),
and the complement of the target's pixels is alpha blended.
As a result, only the part of the source where the grayscale
is not covered by the target is visible.
