ArrayIndexOutOfBoundsException in getLength() method.

[NickUK]

This occurs in the getLength method: (gltext.java: 342)

int c = (int)text.charAt( i ) - CHAR_START; // Calculate Character Index (Offset by First Char in Font)
len += ( charWidths[c] * scaleX ); // Add Scaled Character Width to Total Length

If charAt(i) is a char > 96 (special char) then we get ArrayIndexOutOfBoundsException.
Needs something similar to :

if ( c < 0 || c >= CHAR_CNT) {
