engines: excessive large stroke width has a different visual result. #3668
Description
It seems that only the SW engine has even/odd visual holes. Need to figure out and align the result among engines.

shape1->lineTo(120, 120);

shape1->fill(0, 255, 0);
shape1->strokeWidth(70);

tvg::Matrix m = {10, 0, -600, 0, 10, -500, 0, 0, 1};
shape1->transform(m);
canvas->push(shape1);
return true;
