When I am implementing the IME soft keyboard (#6021 and #6036),
I noticed an issue with PatBlt function.
- Fix the rectangle coordinates when the value was
negative in NtGdiPatBlt function.
- Fix NC_DrawFrame function.
- Fix UserDrawWindowFrame function.
CORE-19334
- Add IntIsWindowSnapEnabled helper function that reads registry value WindowArrangementActive.
- Check the registry and store the value to newly-added g_bWindowSnapEnabled global variable on startup.
- Check the global variable before Window Snap.
Win+Left, Win+Right, Win+Up, and Win+Down can be disabled by registry value WindowArrangementActive.
Snapping mouse can be also disabled. CORE-16379
This fixes regression CORE-16289 where we could not longer
move the taskbar at a different than default location,
as WindowSnap would interfere.
Many Thanks to the patches author Doug Lyons.
Eventually the heuristic that we use here to identify the
taskbar via used window-styles could be improved later.
Theoretically possible that it bails out on some other windows.
The regression was introduced by 0.4.12-dev-373-g

Implemented the following actions: stick the window on the left/right or maximize it,
with the following shortcuts:
- Win key + Arrows;
- drag to left/right screen border;
- double-click on top/bottom.
