Description Rishab Arora 2012-02-26 19:59:24 UTC

Version:           2.0.0 (using KDE 4.7.4) 
OS:                Linux

When I zoom out while viewing constellation lines, I get (apparently) random lines all across the sky. As I scroll, some lines disappear, and others appear.

Reproducible: Always

Steps to Reproduce:
Open Kstars
Turn on Constellation Lines
Zoom Out

Actual Results:  
Random lines across night sky

Expected Results:  
Regular constellation lines

OS: Linux (x86_64) release 3.0.0-16-generic
Compiler: gcc

Git commit 1e4ba1c87357ccfbd3bf7abe2ed9ed8f7e94a2e7 by Jérôme SONRIER.
Committed on 01/03/2012 at 00:35.
Pushed by jsonrier into branch 'master'.

With QPainter, draw a line only if the two points are visible (to prevent random lines with gnomonic projection).
