Is it possible to reuse the allocated memory of an existing ImageBitmap to get another ImageBitmap? I'm asking this for desktop or ios platforms.

For example, on Android, this is possible using the "inBitmap" parameter:

actual fun Source.toImage(existing: ImageBitmap?): ImageBitmap? {
    val options = BitmapFactory.Options()
    options.inScaled = false
    options.inMutable = true
    options.inBitmap = existing?.asAndroidBitmap()

    return BitmapFactory.decodeStream(this.asInputStream(), null, options)?.asImageBitmap()
}
