/* Text bemeretezese pixelre
** A 'selObjText'  elemben levo szoveg font-size-jat csokkenti maximum 'step' lepesben 'dec' pixellel, amig bele nem fer a 'maxWidth' hosszba
** es 'maxHeight' magassagba. Ha ez 'step' lepesben nem erheto el, akkor miutan lecsokkentette a font-sizet amig lehetett,
** a szoveg vegebol annyi karaktert vag le, hogy beleferjen a kivant meretbe, vegere harom pontot tesz.
** A setVisualLength fv a gyujtemeny, ahol az adott szovegekre meghivodik a fuggveny.
** Amire figyelni kell: Ha a bemeretezendo szoveg tobb soros, es egy olyan kontenerben van, aminek a szelessege tobb, mint amekkorara be szeretnenk 
** meretezni, akkor az elso sor kivetelevel a tobbit levagja, mert egeszen eddig nem fog teljesulni a kilepesi feltetel.
** Esetleges fejlesztes:  a selObjTextet ne szovegkent kezelje. Tehat ha van benne nehany node, akkor azokon is fusson vegig, es ami nem fer bele a
** meretkeretbe, azt teljesen dobja ki. (opcionalisan parameterezheto is lehet). Masik, hogy ne a gyujtofvvel kelljen mokolni, hanem legyen egy register
** vagy valami metodusa...
