The return value of RtlFindClearBitsAndSet is an ULONG, assigning it to an ULONG_PTR will not sign extend it. The error value will stay 0xFFFFFFFF. Comparing it to (UINT_PTR)-1 will sign extend and thus compare it to 0xFFFFFFFFFFFFFFFF on x64.
Also use NUM_WINDOW_LESS_TIMERS to initialize the bitmap, rather than the calculated size. This does not make a difference with the current value (32768), but if it was not the case, the bitmap would be larger than this, resulting in invalid bitmap indices being returned, which would cause bugs later on. Finally remove an ASSERT that can be triggered by tests.
Distinguish between the following 3 scenarios:
1. Interactive Winsta0, "Winlogon" desktop: use 128 KB
2. Interactive Winsta0, "Default" & other desktop: use 3 MB (x86) / 20 MB (x64)
3. Non-interactive winsta: use 128 KB
This is what Windows 2003 uses for the interactive desktops on x86 and what Windows 7 uses for x64. Fixes desktop heap exhaustion during testing. The previous value was 512 KB for all desktops.
It doesn't handle the even smaller "Disconnected" desktop, which is only meaningful for RDP sessions and we don't use it anyway.

Clang 13.0.1 was warning about broken 'Ret' handling.
Also remove an unrelated redundant 'else ...'.
Addendum to commit 6dfa71c487 (r68904).
In order for the NT power manager to interact with the Win32 subsystem (thus the whole rest of the system), the Win32 kernel-mode subsystem provides a mechanism that communicates with the kernel power manager via power callouts (aka power requests as per Windows' PDB symbols).
Such mechanism enters in action as soon as Win32 callout routines are estabilished with the PsEstablishWin32Callouts() function.
The NT power manager, the power policy manager respectively, invokes a power callout to denote an exceptional phenomena as a result of power policies or capabilities changes, turning ON/OFF the display, a system time change has occurred, etc.
Such scenarios are described as power events of which the NT power manager sends a WIN32_POWEREVENT_PARAMETERS packet to Win32k via the estabilished "PowerEventCallout" pointer function callout.
For other callouts that inform the Win32 subsystem of impeding power state changes across the system or devices, these are sent as WIN32_POWERSTATE_PARAMETERS packets with its own separate callout.
The purpose of such mechanism is to give Win32k the opportunity to do power related tasks and alert every application of such power events in accordance with what it gets notified by the NT power manager.
Currently this patch stubplements this mechanism in ROS, it is only just the barebones for now. The development of the Win32 power manager will go in parallel with the kernel power manager development (expand, improve, fix the code of issues that whatever may arise).
So far only the PsW32SystemTime power event is implemented for the moment being. This work was decoupled from PR #5719 to avoid clobbering it too much.
=== TODO ===
- Implement power states management communication with the kernel power manager
- Implement the rest of the power events in IntHandlePowerEventWorker
- Implement power event handling in CSRSS (or WinSrv?) which handles any of the events that could not be handled by Win32k otherwise
- Estabilish the power state callout in PsEstablishWin32Callouts() (currently there is no a pointer function that gets assigned to such callout)

Don't free the linked font name if it's already NULL. Since it is allocated only once (when loading the font name from Registry), it should be freed only once too. All subsequent freeing attempts will result in invalid pool freeing.

Addendum to commit 71bed0f5f8 (PR #7123).
The problem in uxtheme was introduced in commit 685084b63c (as part
of a fix for CORE-17203), because it was a copy-paste and adaptation
of the corresponding code in `ntuser/nonclient.c!NC_DoButton()`.
The bugs in `win32ss/user/ntuser/defwnd.c` (and `nonclient.c` as fixed by
the previous commit) were in turn introduced from the migration of menu
and related code from user32 to win32k, see commit 6dfa71c487 (r68904).

Fixes a bug in Midori 0.5.11 installer which caused bad rendering
that was making the text hard to read (no background).
In Windows it's visible as FillRect(0x89011a1f, 0x0019f87c, 0xabababab),
and in ReactOS as SetBkMode(0xb5010fce, -1546139919).
After a number of attempts to get the same behavior, I haven't found a way
to fix it without a hack to make the installer look identical to Windows.
At least I added handling for the incorrect value in SetBkMode.
This shouldn't matter anywhere. It may not look the same as on Windows,
but the text will at least be readable.

Fix wrong MAKEINTRESOURCEW() macro usage cases in LoadCursorW() system-wide.
MSDN documentation for this function states we need to use MAKEINTRESOURCEW() macro only for internal application-defined cursors (loaded from the app instance specified by hInstance parameter), but not for system-defined cursors (those begin with IDC_* prefix), in case when hInstance is NULL.
So get rid from MAKEINTRESOURCEW() macro usage for all cases when hInstance parameter is NULL. And on the contrary, when hInstance is valid and points to the application instance, then use it for the resource identifier.
