This is part of an effort to ensure that all SkPaint effects can only be allocated on the heap. This patch makes the constructors of SkPathEffect, SkXfermode and their subclasses non-public and instead provides factory methods for creating these objects on the heap. We temporarily keep the constructors of the following classes public to not break Chrome/Blink: SkXfermode SkCornerPathEffect SkDashPathEffect BUG=skia:2187 R=scroggo@google.com, reed@google.com, mtklein@google.com, bungeman@google.com Author: dominikg@chromium.org Review URL: https://codereview.chromium.org/166583002 git-svn-id: http://skia.googlecode.com/svn/trunk@13519 2bbb7eff-a529-9590-31e7-b0007b416f81
