Test case: https://upload.wikimedia.org/wikipedia/commons/e/ea/Van_Gogh_-_Starry_Night_-_Google_Art_Project.jpg Image sub-sampling should be enabled for macOS so the number of the decoded pixels is scaled down by the ratio between destinationSize and sourceSize. For non-scaled display, sub-images should be used to display the image on different tiles. The size of the sub-image will be the mapping of the destination rectangle clipped by the GraphicsContext.bounds() in the image rectangle.
