Trying to learn animation stuff here, but it isn't working as documented. I 
have a CALayer installed on my view (subclass of ScreenSaverView). Then another 
CALayer is added as a subLayer on that first layer. At some point after the 
layer has been initially drawn, I want to move it to a new position, so:

self.subLayer1.position = SSRandomPointForSizeWithinRect(NSMakeSize(100, 100), 
self.frame);

Rather than using the default animation timing, it jumps directly to the new 
location. Maybe I'm confused after reading all the docs, but I thought this was 
what Apple refers to as an implicit transaction, and any changes in the layer 
properties would be animated with default values. If not, I guess I'll use the 
more complex explicit transaction methods. Could it be because this is a 
screensaver plugin instead of an app?
