How does DrawScaledObject() reduce images?

Specifically, say i have scaleX and scaleY being 0.5 or 0.25 (i.e. reducing image 2x or 4x). Will each of the new pixels be a kind of "average" (bi-linear or bi-cubic interpolation over 4 or 16 pixels respectively) - or will it pick a single pixel (nearest-neighbour)?

I love your questions, I'm not optimistic about you getting an answer to this one. Just based on what i've seen happen, my guess is bicubic, with nearest-neighbor being the least likely. You can usually tell if its N-N, it really creates a lot of contrast that wasn't in the original.
