branch: master
commit 25636d97bf2f73b0fa7039727350dfefeeeed46a
Author: Mohammad Akhlaghi <mohammad@akhlaghi.org>

    fits-view: only using resolution of primary image
    
    Until now, 'astscript-fits-view' would simply read all the active screen
    resolutions (those with a '*'). However, when more than one display is
    connected to the computer, there will be multiple lines with a '*' in the
    output of 'xrandr'!
    
    With this commit, only the first line with a '*' is used (which is the
    primary display).
