Log:
[win32k]
- For the Low Level Mouse Hook (WH_MOUSE_LL), input can come from the mouse driver or mouse_event. Both of which result in a call to UserSetCursorPos.
UserMode SetCursorPos API also ends up here. Add BOOL parameter that can be used to determine if hooks are to be called.
- Move the code related to calling the hook procedure from MsqInsertSystemMessage into UserSetCursorPos and call the hook procedure here if needed.
If hook procedure returns non 0 value. Dont insert the system message.
- Fixes a recursive call to the hook procedure resulting thread using to much stack exposed by user32 winetest for input.
