/* ********** Function Declarations ********** */
/**
* Function checkWandError() compares the value of $result, which should be
* the result of any MagickWand API function, to explicit FALSE, and if it is
* FALSE, checks if $wand for contains an error condition (in case the API
* function is just returning FALSE as a normal return value).
*
* If the return value is FALSE, and the $wand contains a set error condition,
* the function outputs the error and forcibly ends the program.
*
* If not, returns $result as a reference.
