Overlays not visible in latest stable KStars release on Raspberry Pi

[Hy Murveit]

Patrick,

I believe Jasem provided the capability to disable the image compression in
the KStars Configuration menu, FITS setting.
I have never played with that, but give it a try and let us know if it
makes things better. See the control below.
