Microsoft recently announced Acrylic, the glass-like material in Fluent Design. It's presented as XAML / UWP only, but looks very similar to glass, except it can be arbitrarily tinted and can apply in-app to flyover controls as well as to the app's standalone windows.
The 'recipe' makes it appear as though it's implemented in XAML itself, not being exposed to the wider system.
A related SO question confirms this (it's devoid of concrete, technical answers, but implies acrylic isn't available through the WinAPI the way glass is.)
How would someone mimic this in a plain old Win32 app? Using glass, and blending? (Which APIs, and what's possible in Win10 Fall Update's glass APIs that was not in Win7?) If the app was created with Win32 but used a DirectX surface for rendering, would it open more possibilities?
