[Gzz] 22nd

[Benja Fallenstein]

- small fixes in linebreaking
- cell backgrounds are now shown in gl (i.e., cursors and clones)
- fix linebreaking on *my* screen:

Index: gzz/gzz/view/LinebrokenCellContentView.java
--- 105,136 ----
                            float scale) {
         Object key = new Integer(start+1472);
        s = s.substring(start, end);
+ 
+ 	/**
+         (Benja:) Ouch. The following line makes a great difference, even 
though
+       that should really not be so.
+       
+       Without this line, on *my* system (though not Tuomas'!), the text vobs
+       added by this method extend from 'start' till 's.length()'-- 'end'
+       seems to be ignored. That is, if 's' is "Foo bar baz", 'start' is 4
+       and 'end' is 8, the text shown on the screen is not "bar ", as intended,
+       but "bar baz". (The width used in linebreaking is "bar ", though.)
+       
+       This means two things, apparently:
+       o  My JVM handles substring() virtually, so 's.substring(start, end)'
+          is not a copy of a part of 's', but a subrange of the memory range
+          occupied by 's', starting at 'start' and spanning 'end-start'
+          characters. '""+s', on the other hand, creates a copy of 's'.
+       o  Something on the C++ side does not respect the string length passed
+ 	   to it by the JVM (it presumably thinks the string is 
+ 	   NUL-terminated). So, it displays all the text starting at 'start'
+          till the end of 's'.
+ 	   
+ 	Therefore, please don't remove the following line until you can be sure
+       the bug explained above has been fixed...
+       **/
+       s = ""+s;
+ 
 	if(dbg) pa("addVobs: "+start+" "+end+" '"+s+"'");
         TextVob vob = new TextVob(style, scale, s, key);
         ch.addBox(vob);
