REVISION SUMMARY
  As is KWin only had 1 Cursor which was a singleton. This made it impossible for
  us to properly implement the tablet (as in drawing tablets) support and show where
  we're drawing.
  This patch makes it possible to have different Cursors in KWin, it makes all the
  current code still follow the mouse but the tablet can still render a cursor.

TEST PLAN
  Tests pass, been using it and works okay. Only thing I've noticed broken
  is the screen edges.

REPOSITORY
  R108 KWin

BRANCH
  master
