Also renamed win_printing_context to printing_context_win (correct naming convention) and added stub implementations for _linux and mac. Now all but one file is compiling on all platforms. TEST=none (no functional change). BUG=none Review URL: http://codereview.chromium.org/149212 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@20086 0039d316-1c4b-4281-b951-d872f2087c98
