[Enhancement] Acrylic Theme Title Bar

[Andrew-J-Larson]

When looking at other apps, there is a noticeable difference between how this library enables acrylic vs how it looks from native applications.

In particular, there is a sort of noise texture effect that isn't present from using this library (for example, you can see this in Windows Terminal when acrylic title bar is turned on).

Windows Terminal with the acrylic title bar on:

And it looks like here's the code responsible for that in Windows Terminal:

• See here: https://github.com/microsoft/terminal/blob/9b21b78feea9ff0a0b9ff2c8fa4b4aa5602d3889/src/cascadia/TerminalApp/TerminalPage.cpp#L4682

Additionally, in the Microsoft design docs, it shows that there is a dark and light variant of Acrylic, but I see no options in this library for that (more specifically for setting the title bar theme variant of acrylic)

A good way to explain the noise texture part is this with an example by using the following program: https://github.com/MicaForEveryone/MicaForEveryone/

I used just the regular Acrylic in setting in MicaForEveryone on "Notepad++" to mimic how your library handles the window style currently:

But, if you enable the BlurBehind advanced setting, it replicates the noise that I was talking about:

NOTE: Used GIMP to scale all screenshots to be larger (so that details are more noticeable) with None set for Interpolation (preserves the original pixels).

I'd like to also note that the the title bar, although I was able to get to show the noise texture via MicaForEveryone, there was no option to change the tint (like how it seems to be done with Windows Terminal from its source code).

We are using thin acrylic not normal acrylic.
