Parallel Beauty - with Isolates into the Mandelbrot set
summary
Dart code splits Mandelbrot rendering into multiple Isolates, using spawn, send/receive ports and transferable data to move large Uint32 image buffers without copying. A pool of isolates tracks available isolates and a waiting queue; each tile request carries a request ID and completes a stored Completer when its tile returns. Render time drops as isolates scale to core count (about eight cores hits the sweet spot) and per-tile pooling avoids repeated isolate creation.
