URL: http://svn.reactos.org/svn/reactos?rev=70337&view=rev Log: [MAGNIFY] * Use GetGUIThreadInfo instead of multiple separate "hacks" to obtain all the necessary data in one single call. * Keep the off-screen DC for later use, and only recreate when needed. * Restore caret follow back to default-on. More changes toward CORE-10691
