Lets also turn the this._networkLogLargeRowsSetting setting into the px size so
we can just query the size.

To help with removing @unrestricted lets define this in the constructor.

Done.

[pfeldman, 2017/05/16 22:34:16]

Not a great idea, the setting is the large/small, pixels should not be
configurable.
