REGRESSION (r91125): Polyline tool in google docs is broken https://bugs.webkit.org/show_bug.cgi?id=65796 Source/WebCore: Patch by Stephen Chenney <schenney@chromium.org> on 2011-12-02 Reviewed by Darin Adler. Work around a bug in CoreGraphics, that caused incorrect bounds for paths consisting only of move-to elements. This causes problems in SVG, when the enormous bounds prevented the drawing of things behind. Tests: svg/custom/path-moveto-only-rendering.svg svg/custom/subpaths-moveto-only-rendering.svg * platform/graphics/cg/PathCG.cpp: (WebCore::PathIsEmptyOrSingleMoveTester::PathIsEmptyOrSingleMoveTester): Class to test for isEmpty accoridng ot the same rules as other platforms. (WebCore::PathIsEmptyOrSingleMoveTester::isEmpty): Query the result (WebCore::PathIsEmptyOrSingleMoveTester::testPathElement): Path iterator method (WebCore::PathHasOnlyMoveToTester::PathHasOnlyMoveToTester): Class to test whether a path contains only move-to elements, and hence should have null bounds. (WebCore::PathHasOnlyMoveToTester::hasOnlyMoveTo): Query the result (WebCore::PathHasOnlyMoveToTester::testPathElement): Path iterator method. (WebCore::Path::boundingRect): Modified to check for move-to only paths (WebCore::Path::fastBoundingRect): Modified to check for move-to only paths (WebCore::Path::isEmpty): Now uses the method that matches other platforms. (WebCore::Path::hasCurrentPoint): Now uses CGPathIsEmpty directly (WebCore::Path::transform) : Now uses CGPathIsEmpty directly LayoutTests: Work around a bug in CoreGraphics, that caused incorrect bounds for paths consisting only of move-to elements. This causes problems in SVG, when the enormous bounds prevented the drawing of things behind. Will revert expectation file when expectations are stable.
