Filters the value of an existing transient before it is retrieved.

The dynamic portion of the hook name, $transient, refers to the transient name.

Returning a value other than false from the filter will short-circuit retrieval
and return that value instead.

$pre = apply_filters( "pre_transient_{$transient}", false, $transient );
