1. Add `generics::motion::OffsetPath`, and use specified `Angle` and
computed `Angle` to define specified `OffsetPath` and computed `OffsetPath`.
2. Add `ray` function into `OffsetPath`.
We also tweak the degree from 150deg to 135deg in wpt (e.g.
offset-path-ray-001.html and others) to avoid floating point precision issues.
For example:
```
// offset-path: ray(150deg ...);
// offset-distance: 20px;
matrix:
{
{0.500000 0.866025 0.000000 0.000000},
{-0.866025 0.500000 0.000000 0.000000},
{0.000000 0.000000 1.000000 0.000000},
{10.000000 17.320509 0.000000 1.000000}
}
// rotate(60deg) translate(20px)
matrix:
{
{0.500000 0.866025 0.000000 0.000000},
{-0.866025 0.500000 0.000000 0.000000},
{0.000000 0.000000 1.000000 0.000000},
{10.000000 17.320507 0.000000 1.000000}
}
```
Their translate parts, 17.320509 vs 17.320507, are almost the same (only
tiny difference), which may cause the reftest failed.
