- Known issues remaining with Emscripten:
- The magnitude of wheeling values on Emscripten setups is still mostly wrong. (#6096)
- The magnitude of wheeling values on Emscripten setups is still not great. (#6096)
- When running the Emscripten app on a Mac with a mouse, SHIFT+WheelY doesn't turn into WheelX.
This is because we don't know that we are running on Mac and apply our own Shift+swapping
on top of OSX' own swapping, so wheel axises are swapped twice. Emscripten apps may need
