From 16fccc51456dbab7e392c3952cc367723f9694f6 Mon Sep 17 00:00:00 2001 From: weili Date: Tue, 9 Aug 2016 10:33:10 -0700 Subject: Use smart pointers for class owned pointers For classes under xfa/fxfa/fm2js, and xfa/fxgraphics, use smart pointers instead of raw pointer to make memory management easier. Also fix some styling issues along the changes.
