R devel - Jan 2009 - Automatic shortening of text to fit into area

Hello,

   A comment in engine.c states: "/* don't draw anything; this could  
be made less crude :) */". The following patch makes it less crude: If  
the device doesn't support clipping and the text doesn't fit into the  
area, then remove one character after another from the text until  
either the text fits or the string is empty.

I attached the patch?it's not indented correctly to keep the patch  
size small?and a test script, so you can give it a try. I don't know  
the R core very well, so this change may need some discussion. Yet it  
works for my figures.

Have fun,
   Sebastian

Almost all devices do support clipping, so this is  rather a minority 
interest.

The person who AFAIK worte that comment and designed the clipping in 
the engine is Paul Murrell.  He has been on summer vacation, but it 
looks like he has just returned.  I suggest contacting him directly if 
he does nto respond to these postings.
