[ptx] wanishing points & tiff compression level

[Rich]

two possible problems with hugin 0.5 :

1. see
http://evf.lv/stuff/wanishing_points.tar.bz2 (~3.3mb)
select the middle point in control points tab (in picture). press del on 
keyboard. two points wanish.
sometimes this is also reproducable with points selected from point list 
(below images), sometimes not.
this might be nasty if you delete a point and have zoomed in - you might 
not even notice that another point has disappeared.

2. in sticher tab when compression is selected, field besides it 
(compression level, i assume) is always shaded and is not accessible. is 
this intentional ?
