This makes the cursor pointer held by xf86Cursors.c get reset to NULL whenever the cursor isn't displayed, and means that the reference count held in xf86Cursor.c is sufficient to cover the reference in xf86Cursors.c. As HideCursor may be called in the cursor loading path after UseHWCursor or UseHWCursorARGB when HARDWARE_CURSOR_UPDATE_UNHIDDEN isn't set in the Flags field, the setting of the cursor pointer had to be moved to the LoadCursor paths. LoadCursorARGBCheck gets the cursor pointer, but LoadCursorImageCheck does not. For LoadCursorImageCheck, I added a new function, xf86CurrentCursor, which returns the current cursor. With this new function, we can eliminate the cursor pointer from the xf86CrtcConfigRec, once drivers are converted over to use it.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
