"SVG text doesn't repaint correctly"
* kcanvas/KCanvasContainer.cpp:
(WebCore::KCanvasContainer::computeAbsoluteRepaintRect): Override base class, and apply
appropriate transforms, so damage rects in transformed SVG content get propagated up properly.
(WebCore::KCanvasContainer::getAbsoluteRepaintRect): note a FIXME; this method
seems wrong.
* kcanvas/KCanvasContainer.h: Prototype new method.
* css/svg.css: Don't apply overflow:hidden to foreignObject, since that makes it a RenderLayer
so it paints twice.
* kcanvas/RenderForeignObject.cpp:
(WebCore::RenderForeignObject::paint): Transform the damage rect before passing it down to HTML content,
so everything paints that is supposed to. Also handle opacity here since we won't get layers.
(WebCore::RenderForeignObject::computeAbsoluteRepaintRect): Override base class, and apply
appropriate transforms, so damage rects in HTML embedded in SVG get propagated up properly.
(WebCore::RenderForeignObject::requiresLayer): Never use a RenderLayer.
(WebCore::RenderForeignObject::layout): Make sure to dirty our previous bounds when layout
changes, as by transform.
* kcanvas/RenderForeignObject.h:
* kcanvas/RenderSVGImage.cpp:
(WebCore::RenderSVGImage::paint): Transform the damage rect when painting. Also handle opacity
here since we won't get layers.
(WebCore::RenderForeignObject::computeAbsoluteRepaintRect): Override base class, and apply
appropriate transforms, so damage rects in SVG images get propagated up properly.
(WebCore::RenderSVGImage::translationForAttributes): New helper method, factored out of below.
(WebCore::RenderSVGImage::translateForAttributes): Use above.
(WebCore::RenderSVGImage::requiresLayer): Never use a RenderLayer.
(WebCore::RenderSVGImage::layout): Make sure to properly dirty the old bounds, accounting
for transforms.
(WebCore::RenderSVGImage::relativeBBox): Correct bbox computation.
* kcanvas/RenderSVGImage.h:
* kcanvas/RenderSVGText.cpp:
(WebCore::RenderSVGText::paint): Transform incoming damage rect. Handle opacity here since we
won't get a layer.
(WebCore::RenderSVGText::computeAbsoluteRepaintRect): Apply transforms.
(WebCore::RenderSVGText::requiresLayer): Never use a RenderLayer.
(WebCore::RenderSVGText::layout): Make sure to dirty the old bounds.
* platform/cg/GraphicsContextCG.cpp:
(WebCore::GraphicsContext::roundToDevicePixels): Instead of transforming rect to device space
and back to user space, do this for the origin and lower right corner of the rect. Otherwise the
rect will get inflated if user space is rotated or skewed.
* kcanvas/RenderPath.cpp:
(WebCore::RenderPath::layout): Make sure to dirty the old bounds.
(WebCore::RenderPath::paint): Hhandle opacity here.
Bonus fix:
* kcanvas/RenderSVGImage.cpp:
(WebCore::RenderSVGImage::nodeAtPoint): Fix hit testing. Wasn't applying the x/y
attribute transform.
