When requesting a thumbnail, it's up to the underlying plug-in to honor the
requested size.
If icon == NO, Quick Look will return the plug-in's image result as is.
If icon == YES, Quick Look will force the requested size (because it adds
icon decoration which should match the requested size) - so if you request a
512x512 icon, you should always get a 512x512 image.
Many plug-in just use a low-resolution image stored in the file as a Quick
Look thumbnail. It's totally acceptable but nowadays, "low-resolution"
should be more toward 512x512 than 128x128.
Previews are more complex (generally slower to generate) and are meant to be
displayed mainly in Quick Look panel but they also appear in Cover Flow,
Column view, Info window and, starting with SnowLeopard, in live previews in
Finder's icons.
