  // The additional vertical padding of a bubble.
  LOCATION_BAR_BUBBLE_VERTICAL_PADDING,

  // 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
  // space between the bottoms of most such views and the visible bottoms of the
  // images inside.
  LOCATION_BAR_BUBBLE_ANCHOR_VERTICAL_INSET,

  // The height to be occupied by the LocationBar. For
  // MaterialDesignController::NON_MATERIAL the height is determined from image
  // assets.

  // edges.

  // padding region after the tab's contents region.
  TAB_CLOSE_BUTTON_TRAILING_PADDING_OVERLAP,

  // The horizontal space between a tab's favicon and its title.
  TAB_FAVICON_TITLE_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_PINNED_CONTENT_WIDTH,

  // Height of the region atop the tab bounds that is normally excluded when
  // calculating the tab hit test region or considering where to paint a
  // custom theme background.  (Based on theme behavior it seems like at some
  // point this was added to the area above the top of the tab images, and we
  // now need to subtract it back off to compensate.)

  // row edge.
  OMNIBOX_DROPDOWN_TEXT,

  // The padding inside the tab bounds that defines the tab contents region.
