Subject: Fix frame turning black when reseting theme. Also simplifies the
 frame type changed code somewhat. It turns out the frame still needs to be
 hidden for WM_DWMCOMPOSITIONCHANGED message handlers however. Not sure why,
 but this is the simplest/least buggy this code has been so far so I can live
 with it.
