Reland of place pinch scrollbars with regular scrollbars. (patchset #1 id:1 of https://codereview.chromium.org/1318603005/ ) Reason for revert: After discussion with samuong@, the original patch should be OK to reland as is and https://codereview.chromium.org/1317153002 is an appropriate fix for the crasher.
