All these calls return a version of this image that is scaled proportionally
to the best size. There are two ways the best size can be determined:
a) "fit" - The image is resized so it completely fits into a rect of the
specified size. Nothing of the image will come to lie outside, but there
may be empty areas in the destination rectangle not covered by the image.
b) "cover" - The image is scaled so drawing it into the specified rectangle
will cause the image to leave no empty spots in the rectangle. For this
to look right, some parts of the image may be cut off.
Defaults:
withInterpolation - NSImageInterpolationHigh
andBox - NO
align - NSImageAlignCenter
