Does that explain it?

At first I thought Kevin was somehow referring to icons (?), but the
docs state the same for images as backpatterns:
Cross-platform note: To be used as a pattern on Mac OS systems, an
image must be 128x128 pixels or less, and both its height and width
must be a power of 2. To be used on Windows and Unix systems, height
and width must be divisible by 8. To be used as a fully cross-platform
pattern, both an image's dimensions should be one of 8, 16, 32, 64, or
128.
Well, seems to me that an obsolete state of things is being described here.
Presently I am experimenting with an add-on to my "Imagedata Toolkit"
that creates "seamless tiles" of various sizes and 3 different
algorithms (with 5 options each for the overlapping areas) to create the
tiles. A test button shows the resulting pattern in whole-screen preview.
I experience no limitations so far on MacOS and on Windows concerning
the size of the images or constraints of divisibility. Backpattern
images can be of a size of 500X300 pixels - or *any* other size - on
MacOS and Windows and can have indivisible ratios for example of 151 X 259!
So I am wondering to what Kevin is referring?
