Touch Panel Handler

  FUNCTION: TouchpadEventHandler( msg, x, y)
  - called by user thread(or ISR)
  - msg type 有三种: WIN_PEN_DOWN, WIN_PEN_UP, WIN_PEN_MOVE
  - WIN_PEN_DOWN 
  1. 纪录active元件
  2. 送PENDOWN给元件
  - WIN_PEN_UP 
  1. 取消active元件
  2. 送PENUP给元件
  - WIN_PEN_MOVE 
  1. 在元件范围内送给元件PENMOVE 送CONTROL_ENTER通知AP进入元件范围
  2. 在元件范围外送给元件PENROVE 送CONTROL_EXIT通知AP离开元件范围
  
    FUNCTION: getFocusCtrlHandle
    - 判断是否有元件被笔压下 有则传回其handle 否则传回0
