hasDarkTheme?

[shrike, 2016/03/01 20:30:14]

For the omnibox/location bar, we want the dark style when in Incognito mode, but
we don't want it when we're using a dark custom theme. That's primarily because
the dark style uses a gray background that looks good in Incognito mode but not
necessarily with a dark custom theme. So you will see this special
inIncognitoModeWithSystemTheme with omnibox classes but nowhere else.

 // NSTextField becomes first responder by installing a "field editor"
 // subview.  Clicks outside the field editor (such as a decoration)
 // will attempt to make the field the first-responder again, which
 // causes a select-all, even if the decoration handles the click.  If
 // the field editor is already in place, don't accept first responder
 // again.  This allows the selection to be unmodified if the click is
 // handled by a decoration or context menu (|-mouseDown:| will still
 // change it if appropriate).
