FastTerminal for Java— True-Color retro visualizer in the console!

Witness the absolute limits of the Windows Console & Terminal! Built entirely in pure **Java** using the ultra-high-performance **FastTerminal** and low-level **FastKeyboard JNI** libraries, this demoscene suite pushes text-based rendering into the 21st century.
Using a double-vertical-resolution subpixel layout with half-block character interpolation (`▄`), we achieve full **24-bit True-Color procedural graphics** directly in your command line, fully optimized, 100% time-based, and running at a rock-solid **60 FPS**!

### 🌟 SHOWCASE EFFECTS IN THIS DEMO:
1. **OLED Color Wave (Intro)**: Silky smooth, high-frequency trigonometric gradient waves.
2. **Fluid Gradient & Sinusoidal Plasma Fusion**: An organic 10-second cyclical morph blending multi-directional gradient spans with classic demoscene plasma.
3. **Realistic 24-bit Photo Zoom & Pan**: Volumetric photo pans utilizing an ultra-fast **2D Bilinear Filtering color sampler** for organic pixel blends.
4. **Doom Fire Simulator**: Cellular automata heat propagation with random decay and wind-drifting.
5. **Amiga Checkerboard Zoom & Rotate**: Classic retro grid rotation powered by mathematically pristine **2x2 SSAA (Super-Sampling Anti-Aliasing)**.
6. **3D Wireframe Tumbling Cube**: Perspective 3D projections mapped into a curved starfield warp tunnel, featuring custom-built **Xiaolin Wu subpixel anti-aliased line drawing**.
7. **Lorenz Attractor Particle Swarm**: Chaotic differential equations integrated on a physical timestep.

### 🎮 INTERACTIVE CONTROLS:
Take control of the demoscene live inside the terminal:
* ⬅️ / ➡️ **Left & Right Arrow Keys**: Instantly cycle and skip between effects.
* ⬆️ / ⬇️ **Up & Down Arrow Keys**: Dynamically adjust the cycle duration (in ±5 second steps) live on the fly! The glowing HUD shows the time remaining and current cycle speed.

### 🛠️ UNDER THE HOOD:
* Decoupled **Time-Based Physics**: The animations utilize real-world elapsed seconds and `deltaTime`, allowing perfectly smooth rendering at any frame rate or terminal size.
* Double-Buffered **ANSI Escape Compositor**: Standard output pipes custom, highly optimized diff-sequences to the terminal.
* High-Speed **JNI Focus Gates**: Hooked JNI keystroke queries apply keystrokes *only* when the terminal is the active window!
