/**
 * Compress an ImageData using a simplified JPEG-style pipeline.
 *
 * **Parameters:**
 * - `image_data`: The RGBA ImageData to compress.
 * - `compression`: A value from 0.0–1.0:
 *     - 0.0 = no compression (highest quality)
 *     - 1.0 = strongest compression (lowest quality)
 *
 * **Returns:**
 * A new `ImageData` object containing the visually compressed pixels.
