Platform preferences theme detection

[Christopher Schnick]

Alright, if the accent is not supported yet then almost everything is 
fine I guess. The settings issue is not noticeable as all the updates 
happen very fast.

I want to open my previous question about detecting unsupported colors 
again here. So I assume that for example accent detection is not 
supported on any Linux system and I have not tested yet how widespread 
the support for color scheme detection is on other desktop environments. 
>From an application developer's point of view, the platform preferences 
feature loses some appeal if there is no way of enabling a control flow 
like: If the system color is supported use that one, else use the color 
that I manually define somehow.

So it would be nice to either have a relatively simple way of detecting 
which basic color property foreground, background, accent, color scheme 
is actually supported or allow application developers to set the default 
value for that property manually. In this case, I could just set a good 
looking default accent color, which would then be returned on Linux 
systems as that property is not supported yet.

I don't have access to the JBS, I'm not even sure how you get that.
