I like size because it's nice and short, and it's accurate. 2048x1536 is
a resolution, not a size. Like you said, it's already documented, and if
people looked at other descriptors they should realize that it's not the
same as the horizontal and vertical resolutions.

Yeah, well, I'm to blame for that, I should've reviewed more carefully.
Thanks for bringing that to my attention, I'll go fix those up.
