// text from two different pages at the same time.
//
// The content of the books is drawing (in an endless loop) by local
// script 2007. Changing the page is handled by script 2006, which
// first stops script 2007; then switches the page; then restarts
// script 2007. But it fails to clear the blast texts beforehand.
// Hence, the next time blast text is drawn, both the old one (from
// the old instance of script 2007) and the new text (from the new
// instance) are briefly drawn simultaneously.
//
// This looks like a script bug to me (a missing call to clearTextQueue).
// But this could also hint at a subtle bug in ScummVM; we should check
// whether this bug occurs with the original engine or not.
