- Add UserCreateSystemThread function that will signal csrss to create a new system thread.
- NtUserCreateWindowStation: Create the raw input thread and the desktop thread when the IO window station gets created.
- IntMakeHungWindowGhosted: Create the ghost system thread that will own all ghost windows.
- Let the raw input thread manage the window station of csrss.
[USERSRV] Remove system threads creating hack
- Implement SrvCreateSystemThreads
- Don't create the system threads in UserServerDllInitialization.
- NtUserSetInformationThread: Stub UserThreadUseActiveDesktop and UserThreadRestoreDesktop
- Properly mark the first thread that enters win32k belonging to csrss. At this point we assume that since gpepCSRSS isn't initialized yet, it probably is the first thread.
[WINSRV] Use NtUserSetInformationThread to set the current desktop when needed
-When csrss needs to use user32 or enter win32k, it first needs to assign the current thread to a desktop.
NtTerminateProcess just queues an apc in every thread of the target process which in turn kills each thread. We need to wait so that all processes have enough time to exit before shutting down.
- Implement user32!SwitchToThisWindow by NtUserCallTwoParam TWOPARAM_ROUTINE_SWITCHTOTHISWINDOW.
- Improve user32!CloseWindow with using SetActiveWindow and ShowWindow (synchronized).
CORE-15165
In Windows, user32!CloseWindow minimizes the window. It doesn't close the window actually. This is not a joke. This bad function naming is responsible to MS.
This fix is needed for the Delphi GUI programs.
- Don't enumerate the windows whose owner window exists.
- Use PostMessage SC_RESTORE instead of ShowWindowAsync SW_RESTORE.

[LPK][USER32] Fix reading layout checks.
- Both functions don't care about DT_RTLREADING flag.
- Added a different method to check reading order.
[USER32] Remove gcc-build breaker semicolon.
This function is a condensed version of LpkPSMTextOut() (from lpk.dll),
but not bug-for-bug equivalent.
The main difference is that the underscore is drawn without taking into
account any kind of script processing.
Fixes accessing nullptr / invalid handle in Window->SystemMenu
I could trigger this occasionally when moving Opera 12.18 window
in front of Spotify 1.0.29.92 window.
Fix was:
authored by Thomas Faber (Thank you!)
tested by me
reviewed by James Tabor
Added callback function that redirects calls to GreExtTextOutW that didn't went through lpk BiDi processing, calls that are from the kernel.
Completely solves JIRA issue CORE-6910.
Normally CSRSS must not be connected to any winsta or desktop by default. It should manually connect
to a winsta/desktop only when it has to do some GUI operations, and then disconnect afterwards.
[USERSRV] Temporarily hackfix the harderror dialog display to the current input desktop.

[INCLUDE][SERVICES][WIN32K:NTUSER] Add an undocumented STARTF_INHERITDESKTOP flag
for the STARTUPINFO::dwFlags structure member, whose purpose is to tell Win32k
that the created handles to the window station and desktop to which the
process is connecting to, can be inherited by its child processes.
It is used when starting interactive services.
