+/**
+ * @brief Generates a Tricorn fractal image using an optimized scalar implementation.
+ * @param start The starting complex coordinate (bottom-left or top-left depending on height sign).
+ * @param width The width of the target image in pixels.
+ * @param height The height of the target image. A negative height reverses the Y-axis calculation.
+ * @param res The step size (resolution) per pixel in the complex plane.
+ * @param n The maximum number of mathematical iterations per pixel.
+ * @param color If true, generates a 24-bit RGB image. If false, writes a grayscale image.
+ * @param img Pointer to the pre-allocated memory buffer where the bitmap data will be stored.
