/*! \brief Get the action position.
* \par Function Description
* Retrieves the current action position and stores it in \a x and \a
* y, optionally snapping it to the grid if \a snap is true. This
* should be interpreted as the position that the user was pointing
* with the mouse pointer when the current action was invoked. If
* there is no valid world position for the current action, returns
* FALSE without modifying the output variables.
*
* This should be used by actions implemented in C to figure out where
* on the schematic the user wants them to apply the action.
*
* See also the (gschem action) Scheme module.
*
* \param w_current Current gschem toplevel structure.
* \param x Location to store x coordinate.
* \param y Location to store y coordinate.
*
* \return TRUE if current action position is set, FALSE otherwise.
