[Pkg-chromium-maint] Bug#726531: chromium: Rectangles on canvas are shifted when the zoom factor is not 100%

Package: chromium
Version: 29.0.1547.57-1~deb7u1
Severity: normal

Dear Maintainer,

When drawing rectangles on a canvas tag, the rectangles are not drawn
under the cursor if the zoom level is different from 100%: they are
shifted by a number of pixels which is proportional to the zoom factor.

The bug can be experimented on this page:

Same bug occurs on Windows with Chrome.

Best Regards,
Emmanuel
