  // contained text.
  LOCATION_BAR_BUBBLE_FONT_VERTICAL_PADDING,

  // The corner radius used for the location bar bubble.
  LOCATION_BAR_BUBBLE_CORNER_RADIUS,

  // The vertical inset to apply to the bounds of a location bar bubble's anchor
  // view, to bring the bubble closer to the anchor.  This compensates for the

  // images inside.

  // The horizontal padding between location bar decorations.

  // location bar's children).

  // of the icon view (e.g. does not highlight on hover).
  LOCATION_BAR_ICON_INTERIOR_PADDING,

  // The amount of spacing between the last tab and the new tab button.
  TABSTRIP_NEW_TAB_BUTTON_SPACING,

  // The height of a tab, including outer strokes.  In non-100% scales this is
  // slightly larger than the apparent height of the tab, as the top stroke is
  // drawn as a 1-px line flush with the bottom of the tab's topmost DIP.
  TAB_HEIGHT,

  // Additional horizontal padding between the elements in the toolbar.
  TOOLBAR_ELEMENT_PADDING,

  // The horizontal space between most items in the toolbar.

  // subsequent tab when tabs are stacked.

  // one side)

  // Padding before the tab title.

  // used for all 3 states of normal, hovered and pressed.
