106b12427e
This CL removes the uses of SkNEW that have resprouted since commit
385fe4d, and removes the macros entirely now that Android and Chromium
have been cleaned up to no longer depend on them.
A bunch of files implicitly depend on #include <new> from SkPostConfig.h
still though, so keep that for now. To be fixed in a followup CL.
[mtklein mucking around]
Only public API removed.
