The Dock magnification uses a bitmap interpolation routine that's not
published API yet. It *should* show up in NSImageRep at some point.
I asked Peter Graffigino (sorry if I misspelled that name) about it,
and apparently the image scaling code the dock uses was replaced at
the last minute before shipping 10.0, when it was discovered that the
previous technique made the diagonal cross-hatching on the wastebasket
icon look pretty bad.
Oh, how AWFUL! They couldn't possibly ship it with a bad-looking
wastebasket icon. Hey, put that optimization on hold, the wastebasket
doesn't look nice! Come on, guys, get your priorities right.
This assumes that the person who fixed the image scaling *could* have
contributed to improving app launch times. This is unlikely, since it
takes some time to get your head wrapped around a completely different
project. Having worked on both linkage editors and image processing
code in my time, I assure you that they're *very* different.
Besides, the upshot of making the image scaling work for the
wastebasket, is that Apple now has code that can scale *anything*,
preserving the highest possible image quality in the scaled image. Down
the road, that may very well give us a resolution-independent GUI, which
will be *very* nice when 600DPI LCDs become available.
