03bbfd3183 sw_engine: ignore small cubics 
During the stroke's outline calculation, the function
handling small cubics set all angles to zero. When
the cubic was small but not zero, this resulted in
incorrect outlines. Now such curves are ignored.

ad7c65d2ea renderer: introduced SceneEffect feature 
Scene effects are typically applied to modify
the final appearance of a rendered scene,
such as adding a blur effect.

Each effect would have a different number of parameters
to control its visual properties. The Scene::push() interface
 uses variadic arguments to accommodate various cases.

Users should refer to the SceneEffect API documentation
and pass the parameters exactly as required for the specific
effect type. For instance, GaussianBlur expects 3 parameters
which are:

- sigma(float)[greater than 0]
- direction(int)[both: 0 / horizontal: 1 / vertical: 2]
- border(int)[extend: 0 / wrap: 1]
- quality(int)[0 ~ 100]

and, scene->push(SceneEffect::GaussianBlur, 5.0f, 0, 0, 100);

New Experimental APIs:
- SceneEffect::ClearAll
- SceneEffect::GaussianBlur
- Result Scene::push(SceneEffect effect, ...);

Example:
- examples/SceneEffect

21dad77da6 wg_engine: prevent adding duplicate points while trimming 
In cases where the distance between points is 0, further
processing of the points results in division by zero.
To avoid this check, we ensure that duplicate points are
not added during trimming.
