Bug 30402 – [CHROMIUM] Chromium/skia's canvas isPointInPath() implementation is incorrect

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Stephen White]

See http//crbug.com/7465:

"Canvas exposes the method isPointInPath. According to the spec, "Points on the path itself 
are considered to be inside the path." So that if you create a rect of size 20x20 at 0,0, 
then the point 0,20 should be in the path. We currently return false, because Skia considers 
the point 0,20 outside the bounds of the rect.

Here's a trivial test case:

ctx = document.getElementById("canvas").getContext("2d");
ctx.save();
ctx.beginPath();
ctx.rect(0, 0, 20, 20);
ctx.isPointInPath(0, 20);
ctx.restore();


See LayoutTests/fast/canvas/pointInPath.html for examples similar to this."
