Minor Description
- WM_SYSCOLORCHANGE/WM_DISPLAYCHANGE/WM_WININICHANGE need to be handled to all the propsheet/wizard pages, and to the internal tab control container.
See CORE-13212, commit d09c3d0af8, and PR #9239.
- Send WM_ACTIVATE and WM_ACTIVATEAPP to the property sheet active page.
And do the same with WM_ENABLE, WM_QUERYENDSESSION, WM_ENDSESSION, and WM_DEVICECHANGE, after sending them to the tab control first.
See PR #9239.
Verification of messages ordering on Win2003:
ReactOS setup wizard windows tree:
Spy++ capture settings:
The tested window messages: WM_SYSCOLORCHANGE and WM_DISPLAYCHANGE (note: WM_WININICHANGE not available in Spy++); as well as:
WM_ENABLE, WM_QUERYENDSESSION, WM_ENDSESSION (not directly tested in what follows), and:
WM_DEVICECHANGE, WM_ACTIVATE, WM_ACTIVATEAPP.

We observe that, first, the main wizard window is notified, and then only the current wizard page.
Note that no other wizard page, neither the internal wizard tab control container, are notified there.

We observe that, first, the main wizard window is notified, then all the tabs one after the order in order ("Other page 1, 2, and Current page are respectively: "Intro", "Install type", and "Abort" pages).
Only then, the internal wizard tab control container is notified.

We first get a WM_DISPLAYCHANGE message, followed by WM_SYSCOLORCHANGE. For that latter message also, the main wizard window is first notified, then all the wizard pages in order, and only then the internal wizard tab control container.
