Would be awesome if we could use Remotery to profile C/C++ emscripten games.

Challenges:

1. Websocket server. We can't start a websocket server from an emscripten game. One workaround is to use a native websocket server as a proxy. Another solution is have emscripten directly send the data to another browser tab (postMessage)

2. Timer accuracy. Browsers have recently reduced the accurac

Collect coverage information at end of tests.

1. Pass --coverage option to verilator in makefile
2. Modify c++ test harness to VerilatedCov::write into an output file. There will be one file per test, which should be collected somewhere (this probably needs to be done by test_harness.py)
3. Run verilator_coverage executable,

Show difference quality as a numerical value between original (full size) image and upscaled image in the waif2x implementation comparison chart.

Probably using SSIM. Would be a informative comparison.

OpenCL 2.0 and higher do not require that global work size be a multiple of the local work size. Reflect this in the ccl_kernel_suggest_worksizes function.
