Does this need to be nonzero?  If not, make it zero.  If so, consider setting
all these values to the values they have in the embedder.

I've set the to the values in infobar_view.cc

+const int infobars::InfoBar::kMaximumArrowTargetHalfWidth = 0;
+const int infobars::InfoBar::kDefaultBarTargetHeight = 0;
