This is the first of two patches in this series that removes a large amount of now dead code from dom/plugins as part of removing all NPAPI plugin support. This patch removes re-entrancy guards we have for Windows OnPaint messages, as the guards were only needed for windowed plugins. Differential Revision: https://phabricator.services.mozilla.com/D107144
