Could you confirm that app list looks different on Windows? That is, we don't
want the white background for search box and light gray separator line between
search box and app icon grid.

Nothing drawn here is shown on Windows, except for the bits which peek out from
under the main app list view (e.g. the bubble arrow). I think it would be good
to get this drawn on Windows as well, but it will have to be drawn somewhere
else. I haven't investigated the best way to do this yet, but any and all clues
/ hints / suggestions welcome!

There are padding pixels (controlled by BubbleDelegateView::set_margins) between
bubble contents and border. The padding pixels belongs to BubbleFrameView and in
the border widget on Windows. They could only be drawn by BubbleFrameView and
for now, that is either by a BubbleBorder or a BubbleBackground.

We need to figure out a way to do this properly. But agree that we could punt on
this and do it in another CL.

   const gfx::Rect search_box_view_bounds =
       app_list_view_->ConvertRectToWidget(search_box_view_->bounds());
   gfx::Rect search_box_rect(bounds.x(),
                             bounds.y(),
                             bounds.width(),
                             search_box_view_bounds.bottom() - bounds.y());
 
-  SkPaint paint;
-  paint.setStyle(SkPaint::kFill_Style);
   paint.setColor(kSearchBoxBackground);
   canvas->DrawRect(search_box_rect, paint);
 
   gfx::Rect seperator_rect(search_box_rect);
   seperator_rect.set_y(seperator_rect.bottom());
   seperator_rect.set_height(kTopSeparatorSize);
   canvas->FillRect(seperator_rect, kTopSeparatorColor);
 
   gfx::Rect contents_rect(bounds.x(),
                           seperator_rect.bottom(),
                           bounds.width(),
                           bounds.bottom() - seperator_rect.bottom());
+#else
+  gfx::Rect contents_rect(bounds.x(),

nit: use copy ctor.

[benwells, 2012/08/30 06:51:30]

Done.
