<h3>Log Message</h3>
<pre>Assertion failure under FEImage::determineAbsolutePaintRect()
<https://bugs.webkit.org/show_bug.cgi?id=131660>
<rdar://problem/15669294>
Source/WebCore:
This patch merges Chromium <a href="http://trac.webkit.org/projects/webkit/changeset/149536">r149536</a> (see
<https://chromiumcodereview.appspot.com/14701012>), which moves
m_absoluteTransform out of SVGFilter and into the base Filter class, so
that it isn't necessary to cast a Filter to SVGFilter to get the
absolute transform.
Reviewed by Geoffrey Garen.
Test: svg/filters/feImage-filter-assertion.html
* platform/graphics/filters/Filter.h:
(WebCore::Filter::Filter):
Changed to take the absolute transform.
(WebCore::Filter::absoluteTransform):
Moved from SVGFilter.
(WebCore::Filter::mapAbsolutePointToLocalPoint):
Ditto.
* rendering/FilterEffectRenderer.cpp:
(WebCore::FilterEffectRenderer::FilterEffectRenderer):
Pass a default AffineTransform() to the Filter base class.
* svg/graphics/filters/SVGFEImage.cpp:
(WebCore::FEImage::determineAbsolutePaintRect):
Use the Filter without casting it to SVGFilter.
(WebCore::FEImage::platformApplySoftware):
Ditto.
* svg/graphics/filters/SVGFilter.cpp:
(WebCore::SVGFilter::SVGFilter):
Pass the transform to the base class, and remove initialization of a
removed member var.
* svg/graphics/filters/SVGFilter.h:
Member var moved to Filter.h.
LayoutTests:
Reviewed by Geoffrey Garen.
* svg/filters/feImage-filter-assertion-expected.txt: Added.
* svg/filters/feImage-filter-assertion.html: Added.</pre>
