When changing pointer cursor:
- use PDEV_HARDWARE_POINTER flag if using hardware pointer
- use PDEV_SOFTWARE_POINTER flag if using software pointer
- keep pfnMovePointer as an accelerator to driver function (if available) and never change it
- fix bug (2 pointers) when switching between hardware and software pointer
When moving pointer:
- check PDEV_HARDWARE_POINTER flag to know if we need to call the driver
- check PDEV_SOFTWARE_POINTER flag to know if we need to call EngMovePointer
- search a graphic mode corresponding to real screen resolution (not virtual panning one)
- when capturing the selected mode, copy from input the virtual panning resolution
- when searching the best mode, also try without panning
- Fix Japanese keyboard about [Shift]+[0] and [半/全] (VK_PROCESSKEY).
- Add user32!CliSaveImeHotKey helper function.
- Implement user32!CliImmSetHotKey function. This function is forwarded from imm32!ImmSetHotKey.
- Fix user32!TranslateMessage by using imm32!ImmTranslateMessage.

The problem ReactOS currently faces is this -- whenever the desktop is being parsed we aren't assigning a security descriptor to it. As a matter of fact when Winlogon tries to assign new security information to the application desktop when a user logs in, Winlogon fails because no prior descriptor has been created for it even though we already do this when initializing security buffers in Winlogon.
With that said, we must assign a descriptor when parsing the desktop as well. This fixes a hack in Winlogon where security assigning of application desktop during a log in is disabled (which we can now enable such code path back).
When creating a window station with CreateWindowStationW, the function ignores the security descriptor provided by the caller and instead it uses whatever descriptor the system can find.
Implement a base security infrastructure with code that sets up a security descriptor for the service that we're going to connect through it. Such service is based upon a desktop and a window station.
=== DOCUMENTATION REMARKS ===
The authenticated user, represented by an access token that describes its security context, is the main holder and has ultimate power against the default created desktop and window station objects in USER. The authenticated user in question
is the actual logged in user, this is the case when the server is impersonating a client. Administrators on the other hand have some share of power against default desktop but their power in question is extremely limited against the default
window station as admins can only just enumerate the available and valid handle stations within a desktop.
This fixes the last GetObjectW apitest case:
ok_long(GetObjectA(hBrush, 0, &TestStruct), 0);
- When "cbSize" is "0", GetObjectW shouldn't return "sizeof(LOGBRUSH)" but 0.
- Rely in BRUSH::cjGetObject behavior which returns 0 when cjSize is 0.

When changing current devmode, we must not only change ppdev->pdmwDev
pointer, but also update lots of other structures. This work is done by
PDEVOBJ_lChangeDisplaySettings.
CORE-18169
- do not try to remove ppdev from gppdevList if gppdevList is NULL
- do not check (and maybe change) gpmdev, as it should be done only in MDEVOBJ_vDestroy
The default IME window has to be created for each top-level window in specific condition. It is needed for implementing Japanese input.
- Add IntFocusSetInputContext helper function.
- Call IntFocusSetInputContext after sending WM_KILLFOCUS message.
- Add IntWantImeWindow, co_IntCreateDefaultImeWindow, and IntDestroyOwnedWindows helper functions.
- Create the default IME window (spwndDefaultIme) for the specified window at IntCreateWindow.
- Fix Imm32InternalLockIMC function.
CORE-11700
- Add IntFindNonImeRelatedWndOfSameThread, IntImeCanDestroyDefIMEforChild, and IntImeCanDestroyDefIME helper functions.
- Do assignment unlock spwndDefaultIme at co_UserFreeWindow.
- Destroy the default IME window of the specified window if necessary at co_UserDestroyWindow.
CORE-11700
According to JIRA user simonelombardo, there was crash in exiting a thread.
- Add UserAssignmentLock, and UserAssignmentUnlock helper functions.
- Lock and unlock pti->spDefaultImc by using those helper functions.
CORE-18044
- introduce LDEVOBJ_vDisableDriver (reversal of LDEVOBJ_bEnableDriver)
- introduce LDEVOBJ_bUnloadImage (reversal of LDEVOBJ_pLoadDriver)
- introduce LDEVOBJ_vDereference, to remove a reference to a LDEVOBJ
Also:
- correctly handle success to unload the image, by removing it from pldev list
- correctly handle failure to unload the image, by re-enabling the driver
- simplify EngUnloadImage, as a wrapper around LDEVOBJ_vDereference
- move LDEVOBJ_ulGetDriverModes lower to prevent forward declaration of
LDEVOBJ_vDereference
Unfortunately, disable driver unloading as long as ntoskrnl can't reload
a driver it just unloaded...
- store the acceleration level in PDEVOBJ
- when searching a pdev, search a pdev with required acceleration level
- disable some functions when not at full acceleration level
(levels 3 and 5 are not implemented)
Initialization of device mode list will be done later, just before switching to graphics mode.
If no graphic display is available, we will now fail when starting first GUI application in
co_IntGraphicsCheck(). Add a bugcheck here to prevent frozen screen.
This function can create a MDEV for the whole display (maybe containing multiple
PDEVs), or update settings of a specific PDEV.
- call PDEVOBJ_lChangeDisplaySettings when switching to graphics mode.
- modify EngpGetPDEV to search requested PDEV only in current MDEV
This will be used (later) to store the list of all enabled display devices.
Add a global variable gpmdev (should really be stored in DISPLAYINFO structure)
Replace global variable gppdevPrimary by pmdev->ppdevGlobal.
- change first argument to be a PGRAPHICS_DEVICE instead of a device name
- add ldevtype (for now, only LDEV_DEVICE_DISPLAY is allowed)
- always pass a devmode if ldevtype is LDEV_DEVICE_DISPLAY
- insert the ppdev into gppdevList on success
- change callers to adapt them to new rules
