Issue with Bitmap width and height setters

Help
#1

I was having problems setting a Bitmap’s width and height, and I think I may have found an issue that appears to be related to this. In the Bitmap class the width and height setters are of the form:

@:noCompletion private override function set_width(value:Float):Float
{
	if (__bitmapData != null)
	{
		if (value != __bitmapData.width)
		{
			__setRenderDirty();
			scaleX = value / __bitmapData.width;
		}
		return value;
	}
	return 0;
  }

The problem arises when trying to set the width or height of an already scaled Bitmap to the same value as the width or height of that Bitmap’s bitmapData. If I understood this correctly, in this case the setters will ignore the given input value (“if (value != __bitmapData.width)”), thus the Bitmap’s scaleX or scaleY member (which is already != 1.0) will remain unchanged, and as a result the width or height of the Bitmap will not correspond to the given value.

I was able to correct the problem in my program by using the Bitmap’s scaleX and scaleY members directly instead of using the Bitmap’s width and height setters.

I think this should fix it:

Setting scaleX or scaleY should trigger the dirty flag automatically if the value is different

Thank you very much for the quick reply and fix!
