Instruccions:
Dibuixa línies clicant al botó esquerra, fes un reset clicant al botó dret.

//També si està apretat el color de la linea cambia depenent de l’eix on tinguis el mouse, i assignem la transparència a 100, per tant depenet de la velocitat del mouse, es veu d’una manera o altra.

//Si està apretat el botó dret, s’esborra la pantalla.
