Circles are rendered incorrectly

Circles don't close completely, you can see an opening on the right side.

Code:
```kotlin
import korlibs.image.bitmap.*
import korlibs.image.color.*
import korlibs.korge.*
import korlibs.korge.scene.*
import korlibs.korge.view.*
import korlibs.korge.view.align.*
import korlibs.math.geom.*

suspend fun main() = Korge(windowSize = Size(512, 512), backgroundColor = Colors["#2b2b2b"]) {
val sceneContainer = sceneContainer()

sceneContainer.changeTo { MyScene() }
}

class MyScene : Scene() {
override suspend fun SContainer.sceneMain() {
val cellSize = 128
image(Bitmap32(cellSize, cellSize).context2d {
val margin = 20
stroke(Colors.GREEN, lineWidth = 6) {
circle(Point(cellSize / 2, cellSize / 2), (cellSize - margin) / 2)
}
}) {
centerOn(this@sceneMain)
}
}
}
```

Output:

System:

Start by running the provided Kotlin snippet and inspect the Bitmap32 context2d circle rendering path, especially the circle call inside the stroke block. Confirm the issue on the reported setup, then verify that the rendered circle closes completely without changing the example's intended size or stroke.
