- I_CheckNativeMouse() now checks the foreground window to determine if the

mouse should be grabbed. This fixes the case where you start the game in
  the background and it grabs the mouse anyway.
- Changed raw mouse grabbing to call ShowCursor() directly instead of through
  SetCursorState(), since changing the pointer isn't working with it
  (probably due to the lack of legacy mouse messages), and the others work
  fine by setting an invisible cursor.
- Fixed: Raw mouse input passes wheel movements in an unsigned field, but the
  value is signed, so it requires a cast to use it.
- Reverted accidental changes to src/sdl/i_input.cpp.
