Hi Igor2,

I have applied the diffs r975 and r976 to the "home/bert/cycdrag" branch 
in vanilla pcb.

Now I have to start testing ;-)

For diff r977 (implementing the "envelope" versus "intersect" selection 
behaviour) I get the impression that this one is not related to 
cycle-drag selection.

If added it may cause a breach of the principle of "least surprise" if 
not fully grasped by the testers/reviewers.

I'd better put this one in a separate topic branch to be reviewed on its 
own merits.

More testing to do.

Thanks for the diffs and kind regards,

Bert Timmerman.
