nit: NOTIMPLEMENTED()

[oshima, 2013/01/30 23:45:53]

I used to put NOTIMPLEMENTED for blank method, but I'm a bit annoyed by
the fact that we're doing it for the method that doesn't have to be
implemented (which print out unnecessary warning message).

I understand that that's necessary for the method that should/will be
implemented (like OnDeviceScaleFactorChanged), but i think NOTIMPLEMENTED
isn't necessary for this case. WDTY?

[Daniel Erat, 2013/01/30 23:52:45]

I think it makes sense to use NOTIMPLEMENTED() even if you don't have plans to
implement it (or maybe even NOTREACHED() if it should really never be called). 
If someone calls this method on a platform where it isn't implemented, it's
useful for them to see an error.

[oshima, 2013/01/31 00:04:56]

Ok, NOTREACHED makes sense for this case. I just thought that a method that is
intentionally left blank shouldn't be considered an error or marked as
"should be implemented".
