+    An image that will be resampled before it is drawn.
+
+    A plain Image only stores plain pixels, but does not store any information
+    about how these pixels correspond to points. This means that if the image's
+    dimensions are interpreted as points, then the image will be blurry when
+    drawn on high resolution displays. If the image's dimensions are instead
+    interpreted as corresponding to exact pixel positions, then the logical
+    size of the image will change depending on the scale factor of the screen
+    used to draw it.
+
+    The ScaledImage class is designed to store an image alongside a scale
+    factor that informs a renderer how to convert between the image's pixels
+    and points.
