Added

  • Text alignment — drawText() now accepts align: "left" | "center" | "right" option for horizontal alignment relative to the given x position. Works with both bitmap and MSDF fonts.
  • Color mutating functions — setAlpha(color, a), setRgb(color, r, g, b), and lerpColorInto(target, start, end, t) for zero-allocation color manipulation in hot loops. JSDoc perf warnings added to rgb() and withAlpha().
  • Global particle cap — setMaxTotalParticles(n), getMaxTotalParticles(), getTotalParticleCount() to enforce a memory ceiling across all emitters (default 10,000). Warns once at 80% capacity.
  • Frame profiler MCP tool — get_frame_stats returns {frame_time_ms, draw_calls, fps}. Slow-frame warning (>32ms) printed to stderr automatically. Available via HTTP inspector at /frame_stats.
  • Hot-reload watchdog — persistent watchdog thread detects stuck frames (>2s timeout), forces reload on next frame. MCP hot_reload tool bypasses blocked main thread directly via AtomicBool.
  • Circle texture batching — drawCircle() now renders a single anti-aliased sprite instead of ~80 scanline sprites. New uploadRgbaTexture() API for uploading raw RGBA pixel data as textures.
  • Auto-assign free ports — MCP and inspector servers automatically find free ports instead of failing on conflicts.
