Just double checking that these are supposed to be empty.

Yes. For ldpi, I manually calculated the values for the last frame based on .75
* mdpi values. I didn't want to hand calculate all of the other frames (it
likely wouldn't have looked right anyway), so for ldpi we never animate and
always just show the last frame.
