/**
 * Creates a texture atlas from an array of ImageData objects.
 *
 * A texture atlas is a single large texture that contains multiple smaller images.
 * This allows efficient rendering by reducing the number of texture bindings needed.
 *
 * The atlas uses a grid layout where each image gets a square region sized to
 * accommodate the largest image dimension. Images are placed left-to-right, top-to-bottom.
 *
 * @param imageDataArray - Array of ImageData objects to pack into the atlas
 * @param webglMaxTextureSize - WebGL maximum texture size limit (default: 16384)
 * @returns Atlas data object containing:
 *   - atlasData: RGBA pixel data as Uint8Array
 *   - atlasSize: Total atlas texture size in pixels
 *   - atlasCoords: UV coordinates for each image as Float32Array
 *   - atlasCoordsSize: Grid size (number of rows/columns)
 *   Returns null if creation fails or no valid images provided
