Mouse Cursor Problems

My diagnosis for the original problem was 'unnecessary warping'.  This 
situation arose when the XServer was charged with drawing the cursor and 
dinput thought it was drawn by the game.

I fixed RCT2 by selectively disabling the warping mechanism when the game 
requests mouse data.

However, this is not the only time when warping is applied.  Warping is 
also sometimes applied when the mouse is acquired 
(in SysMouseAImpl_Acquire). If the mouse is warped when it is acquired and the
XServer is later charged with drawing the cursor, the position of the 
cursor on the screen may be out of sync with where the game thinks it is.

IMO the warping inside SysMouseAImpl_Acquire serves no purpose and can be 
commented out.  This should solve the syncing problem.  It should not 
cause any other ill-effects though.
