// WM_MOUSEWHEEL, WM_MOUSEHWHEEL, WM_VSCROLL, and WM_HSCROLL, used to work
// around issues with out-of-process NPAPI plugins.
//
// (There may yet be old third-party apps that unwisely send these messages
// directly to our windows to cause scrolling; we should probably avoid reusing
// them for a while, so as not to have to worry about that.)
