[cairo] Clamp the clip rect expanded to the infinity
https://bugs.webkit.org/show_bug.cgi?id=228920
Reviewed by Simon Fraser.
If overflow-x is clip, RenderBox::overflowClipRect expands the clip
rect in Y axis by using LayoutRect::expandToInfiniteY. Same for
overflow-y. It uses values of LayoutUnit::nearlyMax. LayoutUnit is
using 26.6 fixed point numbers while cairo is internally using 24.8
fixed point. Such clip rects were causing overflow.
* LayoutTests/platform/glib/TestExpectations:
* Source/WebCore/platform/graphics/cairo/CairoOperations.cpp:
(WebCore::Cairo::clampClipRect): Added.
(WebCore::Cairo::clip): Clamp the passed clip rect.
