Tested on macOS:

1. Install the CodeLLDB VSCode extension. Unlike the debugger in the C/C++ extension, this allows to set breakpoints inside Zig "test" blocks (in the MS C/C++ extension debugger, breakpoints inside test blocks will be disabled once the debugger starts for unknown reasons.
2. When compiling the test, tell it to also emit a binary: zig test -femit-bin=zig-out/bin/my-test src/bla.zig, otherwise there will be no executable to debug.
3. The compiled test executable expects the path to the Zig executable as first command line argument, the launch.json file needs to be setup accordingly (note the args item):

My Dear Imgui render loop looks a bit unusual because I want to reduce calls to WebGL as much as possible, especially buffer update calls.

This means:

• only one buffer each for all per-frame vertex- and index-data
• only one update call each per frame for vertex- and index-data (with my own double-buffering, since buffer-orphaning doesn't work on WebGL, and with this I'm also independent from any 'under-the-hood' magic a GL driver might or might not perform)
