0.1.0

Overhauled to be more flutter like!

0.0.1

Added

• Color Interpolation APIs:
  • drawLineColored: Bresenham line drawing with linear color gradients.
  • fillTriangleColored: Scanline-based triangle rasterizer with 3-way vertex color interpolation (RGB Triangle).
  • fillQuadColored: Bilinear quadrilateral rasterizer with 4-corner color interpolation (Bilinear Quad Gradient).
• Per-Cell Style Overrides: Added a custom List<Style?> _styles override grid to the Canvas widget, allowing custom coloring on a per-cell basis while falling back to the default widget style.
• Interactive Pause Control: Added a keyboard binding for the P key to pause/resume the shape rotations and radar sweeps in real-time, displaying [PAUSED] or [RUNNING] in the demo header.
• High-Fidelity TUI Showcase:
  • Styled the Analog Clock with custom amber ticks, steel face outlines, and sweeping color-coded hands.
  • Colored the Radar scopes and cross-hairs in forest green, sweep lines in bright neon green, and fade-out blips in amber/orange.
  • Integrated rotating outline and filled RGB triangles/quads using the new color interpolation APIs.

Changed

• Gap-Free Rasterization:
  • Replaced the edge-sweep triangle filler with a mathematically sound scanline rasterization algorithm to guarantee 100% solid fills with no empty cells or gaps at any rotation angle.
  • Quad rasterization now splits the polygon into two adjacent scanline-rasterized triangles, ensuring zero-gap fills.
• Project Renaming: Renamed the codebase/package from cli_experiment to termui in pubspec.yaml, package lock configuration, and all 86 project-wide Dart source imports.

Fixed

• Fixed sub-pixel coverage gaps inside the rotating triangles and squares where the lines would fan out and leave unfilled cells.
