Bug 41192 – Canvas: bezierCurveTo() and quadraticCurveTo() must ensure subpaths

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Andreas Kling]

CanvasRenderingContext2D's bezierCurveTo() and quadraticCurveTo() should implicitly moveTo() the (first) control point if the current path is empty.

This test (on IE Test Center) fails:
http://samples.msdn.microsoft.com/ietestcenter/html5/canvas/canvas-complexShapes-bezierCurveTo-001.htm

This is also covered by (skipped) in-tree tests:
canvas/philip/tests/2d.path.bezierCurveTo.ensuresubpath.2.html
canvas/philip/tests/2d.path.quadraticCurveTo.ensuresubpath.2.html
