Scaling down an image does not work as intended. The image only scales down when it's corners touches the respective corner of the screen.
Using a 320x320 image and setting the image component's properties thus:
+ image {
top = 100%-20
left = 100%-20
width = 20
height = 20
theme_dir = "/usr/share/grub/themes/demo/images/"
file = "gnu320.png"
}
scales the image to 20x20 as expected. See screenshot: bug-image-scaling-1.png
However, using the same image, and setting the image component's properties thus:
+ image {
top = 80%
left = 80%
width = 20
height = 20
theme_dir = "/usr/share/grub/themes/demo/images/"
file = "gnu320.png"
}
does not scale the image to 20x20. See screenshot: bug-image-scaling-2.png. The image is actually scaled to fit the area between 80% and 100% of the screen's dimension.
This shows that the image is not scaled if it's edges does not touch the respective screen boundaries:
+ image {
top = 0
left = 368
width = 20
height = 20
theme_dir = "/usr/share/grub/themes/demo/images/"
file = "gnu320.png"
}
See screenshot: bug-image-scaling-3.png
If the same image is used as an icon for the menu items, it scales properly. See screenshot: icon-scaling-1.png

It's because image exercises pressure in order to be at least as big as
source image. We could add a new parameter minimum_width/minimum_height
but it would be a feature and I doubt it's worth breaking freeze for this
