Creates a bitmap image display showing either a
draw.Bitmap instance or one that is loaded from a
specified file path.
When size has #false for a dimension, then the size
of content is used. Within that size, the image is either
scaled to fit in both dimensions when display is
#'fit, or it is stretched to fill in both dimensions when
display is #'fill.
If the image view has a different size based on min_size and
stretch, then the image is centered within the view’s area.
Scaling options for
Image.
