Two cursor using Xinerama on XServer

    I have tried it, but it becomes worse. There are some cursors on the edge of the screen when I move the pointer.
    I'm afraid that the changes are still not correct.
Best wishes,

This fixes it on my box, please give it a test.

Subject: [PATCH] xfree86: fix SWCursor check in xf86CursorSetCursor.

Wrong check for inputInfo.pointer resulted in a SW cursor being rendered when
the pointer left the screen (in a Xinerama setup).
We must call the sprite rendering function if
- SW cursors are enabled, or
- The current device is not the VCP and not attached to the VCP.
