In Image constructor, requestedWidth is passed instead of requestedHeight

[KSwordOfHaste]

I noticed that the parameter of three Image constructors may be incorrect.

please check scalafx/scene/image/Image.scala: near line 51, 67 and 73

 def this(inputStream: InputStream, requestedWidth: Double, requestedHeight: Double, preserveRatio: Boolean, smooth: Boolean) =
   this(new jfxsi.Image(inputStream, requestedWidth, requestedWidth, preserveRatio, smooth))
...

In these constructors, requestedWidth is passed instead of requestedHeight as the third argument.
