<h3>Log Message</h3>
<pre>Outline with auto style leaves bits behind when the the box is moved.
https://bugs.webkit.org/show_bug.cgi?id=148100

Reviewed by Simon Fraser.

Source/WebCore:

We paint the focus ring when 'outline-style: auto' is present, however
we don't take the focus ring width into account when the repaint rect
is computed.

Tests: fast/repaint/outline-with1px-auto-repaint-rect.html
       fast/repaint/outline-with2px-auto-repaint-rect.html
       fast/repaint/outline-with3px-auto-repaint-rect.html

* rendering/RenderObject.cpp:
(WebCore::RenderObject::adjustRectForOutlineAndShadow):
* rendering/RenderThemeMac.h:
* rendering/RenderThemeMac.mm:
(WebCore::RenderThemeMac::platformFocusRingMaxWidth): Deleted. : 0 as focus ring width is incorrect.
The reason why <a href="http://trac.webkit.org/projects/webkit/changeset/169699">r169699</a> fixed the failing cases was because they all had outline width &lt; 3 (but no auto outline style).
The correct fix is to check if the style requires focus ring painting and use the RenderTheme::platformFocusRingMaxWidth
accordingly.

LayoutTests:

Due to RenderView::maximalOutlineSize() each outline width need to be tested separately.
