[Kstars-devel] [PATCH] transparency for infoboxes and labels

[Médéric Boquien]

Hello,

I have made a small patch improving the transparency effect:
* for infoboxes, i have replaced the box background pattern by a solid colour 
and an alpha value of 127. The value is somewhat arbitrary but it looks fine 
with all colour schemes i have tried. Look at the 2 attached png images to see 
the difference.
* for labels, i have also replaced the pattern with a solid colour. To perform 
the fading effect, rather than manually calculating a new colour as done 
before, i keep the same RGB values for the label background but i increase the 
transparency to make the label more and more transparent.
So far, i have not seen any problem/

Thanks, regards,

Médéric
