*   the display controller supports these features.
*
* Parameter:
*   LayerIndex - Index of layer to be configured
*   Cmd        - Please refer to the details in the switch statement below
*   pData      - Pointer to a LCD_X_DATA structure

* Return Value:
*   < -1 - Error
*     -1 - Command not handled
*      0 - Ok
