/**
 * Wipes all request vars and sets a new holder map.
 * <p>
 * Attempts to set the same map for as many contexts present as possible, for compatibility.
 * <p>
 * <em>NOTE:</em> in some cases this call is not necessary, but it's a good idea anyway
 * because it will set the same map for request and context (but not ftl - FIXME?),
 * which might prevent problems in odd rendering cases.
 * This should be called at beginning of rendering at a point where as many of the parameters
 * are non-null as possible (but env will probably usually be null).
