To hypothetical future sync'ers: If you ever try to sync this file with
MinGW-w64, please be extremely careful to port all the fixes (including
x64-compatible casting fixes, missing definitions, etc.) that have been
brought to this file along the years by your dear ReactOS colleagues.
I want to visualize the message stream and verify the states of each message. ROSTESTS-328
- Add a testcase named MessageStateAnalyzer into user32_apitest.
- Also fix type casts in <windowsx.h>.
- Add the following macros into <windowsx.h> header: HANDLE_WM_COPYDATA, HANDLE_WM_DEVICECHANGE, HANDLE_WM_DISPLAYCHANGE, HANDLE_WM_HOTKEY, and HANDLE_WM_MOUSEWHEEL.
- Fix HANDLE_WM_CONTEXTMENU macro.
- Make sure the DWLP_* values are correct on _WIN64
- Don't use the DWL_* constants, they are not portable. Enforce this by removing them entirely from winuser.h
- Make sure Get/SetWindowLong*Ptr* is used and pointers are not truncated to LONG
