Calculate Mandelbrot images on the GPU using CUDA, via the Numba compiler. The result is shown on a web page at http://localhost:12345 where it is possible to zoom and pan using the keyboard (w,a,s,d,j,k,l).
Tested on Ubuntu 22.04 LTS with these dependencies:
sudo apt install nvidia-cuda-dev nvidia-cuda-toolkit
A non-ancient NVIDIA GPU is required.
