0. Use LDC. It is significantly faster.
1. Utilize the fact that the Mandelbrot set is symmetric about
the X axis.You can half the time taken.
2. Use std.parallelism for using multiple cores on the CPU
3. Use @fastmath of LDC
4. imageData.reserve(width * height * 3) before the loop
5. [1] is a great article on this specific topic
