RE: Dark mode on Windows

[Vince Salvino]

I originally tried dynamically loading dwmapi.dll, and it cannot be done 
dynamically. It will simply not load. I spent a lot of time head-scratching in 
gdb to figure this out. From what I read, it behaves a bit differently than 
other DLLs and has to be linked. This is also my first foray into Win32 
programming, so I have exactly zero experience with any of this stuff, and 
could be wrong.

But in that case, the decorations can't be controlled on a per-frame basis.  
This behaviour is desirable and could potentially drive people to use 
proprietary operating systems.

If you find a solution, I can help test on Windows 9x.  But first, is there any 
reason `DwmSetWindowAttribute' can't be dynamically loaded, like many other 
functions are on MS-Windows?
