GDIPlusSVGPath::MoveTo need a mPath.StartFigure

Hi, I try a svg file at https://www.w3schools.com/graphics/tryit.asp?filename=trysvg_path, and found different render result with gdiplus ports

I tried add `StartFigure ` at `MoveTo` and works ok

```cpp
void GDIPlusSVGPath::MoveTo(float x, float y)
{
mPath.StartFigure(); // add StartFigure at here
mCurrentX = x;
mCurrentY = y;
}
```

svg file:
```xml

```

Start at GDIPlusSVGPath::MoveTo and reproduce the rendering difference with the linked SVG path example. Compare the result with and without mPath.StartFigure(), then verify that the affected paths render consistently without changing unrelated SVG path behavior.
