Feature: Support changing luminosity of Acrylic backdrop

[XiaoTDM]

What feature or improvement do you think would benefit Files?

Add an extra option to control whether Files is allowed to use the system Mica as the background layer directly (i.e., use the system title frame directly).

I am using DWMBlurGlass, which works very well in various default WinUI 3 programs, and I hope Files can support it too. Since the principle of DBG is to replace the rendering of system background frame, it can be achieved as long as Files uses system frame.

I think it would be nice to allow the luminosity of Acrylic to be modified.
Now it only has Acrylic Base (~50%) & Thin (~90%).

Requirements

- Add a 'System Default' option to the 'Appearance - Background Material' drop-down menu;
- Modify the logic for the application background so that when the above option is selected, it directly reverts to the system-level background.

Thank you for your feedback, do you mean to not extend into the title bar? If so, this adds a layer of completely around the tab bar and the entire interface that we would like to avoid.

I used translation software, and it seems that some details were lost.
What I roughly mean is to let Files support using Window.SystemBackdrop API, so that DBG's custom blur effect can be applied to Files.

Files already uses the regular backdrops supported by WinUI.

I don't know how to put it.
The current backdrops cannot be replaced by DWMBlurGlass, I want it to use the default backdrops drawn by DWM directly instead of what Winui provides, like Explorer, Paint and Notepad.

We're using the regular backdrops in WinUI. If it doesn't already work, it could be that DWMBlurGlass WinUI isn't compatible with WinUI.

If this is not supported, I think it would be nice to allow the luminosity of Acrylic to be modified.

This is something we can consider 👍
