AcrylicDemo — Porting rust-acrylic-demo in Delphi (WinRT)

Port of https://github.com/thisKai/rust-acrylic-demo using the Delphi WinRT units (Built-In Delphi winrt Units).

Snapshot:

Rust file	Delphi unit
interop.rs	Acrylic.Interop
window_target.rs	Acrylic.Interop (ICompositorDesktopInterop) + Acrylic.Host
window_subclass.rs	Acrylic.Window
main.rs effect graph	Acrylic.Effects + Acrylic.Host.BuildAcrylicEffect
main.rs Win2D noise	Acrylic.Graphics + Acrylic.NoiseData
main.rs rest	Acrylic.Host

Add the winrt folder to the project search path (Winapi.UI.Composition, Winapi.Foundation, Winapi.CommonTypes, Winapi.SystemRT, Winapi.Storage.Streams are needed). Target: Win64 or Win32, Windows 10 1803+.

What is different from the Rust version

• Win2D is gone. The Rust code uses Win2D (win2d_uwp) for the effect classes, CanvasDevice and CanvasBitmap. Your winrt units have none of that, so:
  • the effect classes are replaced by TD2DEffectNode (implements IGraphicsEffect, IGraphicsEffectSource and IGraphicsEffectD2D1Interop directly on the D2D1 effect CLSIDs);
  • CanvasDevice/CanvasBitmap are replaced by D3D11 + D2D device + WIC (PNG decode) writing into the composition drawing surface.
• noise.png is embedded as a byte array (Acrylic.NoiseData), like include_bytes!.
• winit is replaced by a plain Win32 window + message loop (no VCL, so nothing paints over the surface).
