File        : WM_Timer.c
Purpose     : Implementetion of WM_CreateTimer, WM_DeleteTimer
              for systems with external one shot timers.
              (--> Philips, 2003)

              This module requires 2 macros in order to work and
              generate code:
              GUI_X_CREATE_TIMER(Period, void (*cb)(int))
              GUI_X_DELETE_TIMER(ID)

              Note that the delete macro is optional, since
              one-shot-timers are expected to delete themselves.
