Pressing Alt toggles picking mode. This is fine for keyboard and mouse usage,
but some use cases, such as disabling picking mode when a finger is placed
on a thumbstick and enabling it back when it's lifted, require finer control.
Allow to always enable picking mode when pressing Alt with Shift, and to always
disable picking mode when pressing Alt with Ctrl.
With tonemapping, clouds need to stand out above 1.0 to reach proper
white levels.
Note that this should get disabled if tonemapping isn't used, in case
it's made properly configurable in the future.
We're supposed to output linear values there, as sRGB transfer function
gets applied either by GL framebuffer or FBOUT later on.
min_ev and max_ev also need to be adjusted, as they're tweaked for
a pipeline with exposure compensation. The current values lead to a very
washed-out image, which was "hidden" by subsequently applying gamma twice.
It may make sense to revisit these values in the future to better match
the rendering pipeline.
Shift isn't used as that would affect joystick controls and we
probably should discourage the user from roaming around in external
cam mode too much, so they won't forget that they're not in regular
free fly out of the cab.
Both setweather and settemperature expect overcast as their second
parameter. Passing zero to settemperature always overwrites whatever
gets passed to setweather.
Three small source tweaks that let the OpenGL renderer build and run
on Apple Silicon without affecting the Windows/Linux paths:
- stdafx.h: use GLM_FORCE_NEON on ARM64 instead of GLM_FORCE_AVX2.
AVX2 pulls <immintrin.h>, which clang on ARM64 rejects because
the x86 intrinsics are unimplemented.
- utilities/utilities.cpp: provide an Apple libc++ fallback for
Now() using localtime_r + strftime, since
std::chrono::current_zone() is not yet implemented there.
- audio/audio.h: prefer Khronos-style <AL/al.h> headers when they
are on the include path (brew openal-soft) and fall back to the
deprecated Apple OpenAL.framework's <OpenAL/al.h> only otherwise.
