vector: add (*Path).AddPathStroke reimplement DrawFilledPath and StrokePath
...
The new implementation uses Evan's method [1] using texture representing
a stencil buffer instead of the graphics library's stencil buffer.
This simplifies the implementaiton of the graphics drivers, and enables
better anti-alias without changing the rendering cost.
Also, this fixes an issue of line rendering quality
This change deprecates some existing APIs like DrawImageOptions.AntiAlias
and FillRule. Users should always use DrawFilledPath or StrokePath.
