A new external MSAA setting was introduced in https://github.com/godotengine/godot/pull/33518
that fixed issues on GLES2 and Oculus Mobile VR. To avoid misunderstanding it was suggested
by @BastiaanOlij and discussed on discord to rename it to AndroidVR.
A change in upstream Emscripten 1.39.1+ made our buildsystem error
out where it was previously only issuing a warning:
```
[ 5%] Linking Static Library ==> main/libmain.javascript.opt.bc
shared:WARNING: Assuming object file output in the absence of `-c`, based on output filename. Please add with `-c` or `-r` to avoid this warning
Ranlib Library ==> main/libmain.javascript.opt.bc
/opt/emsdk/upstream/bin/llvm-ranlib: error: unable to load 'main/libmain.javascript.opt.bc': file too small to be an archive
```
As advised on emscripten-core/emscripten#9806, we should be using
`emar` here to create the static library and not `emcc`.
This was apparently done to workaround Emscripten issues in the past,
but evidently this is no longer necessary.
The rest of the `env` redefinitions should probably be re-assessed
against the current state of Emscripten.
Fixes#33374.
The Mono IL interpreter's WebAssembly to native trampolines don't support passing structs by value, so we need to do it this way.
Also now we pass and return long, ulong, float and double as ref parameters as well. This is due to missing trampolines for float and long types. This is likely a temporary workaround that will be reverted in the future. The correct solution would be to patch 'mono/mini/m2n-gen.cs' when building the Mono runtime for WASM in order to generate the trampolines we need.
This makes it easier to navigate in 3D when using a graphics tablet.
This fallback modifier will only be available if no other modifier
is using Alt.
This partially addresses
https://github.com/godotengine/godot-proposals/issues/196.
Messages coming from ERR_EXPLAIN / ERR_*_MSG macros used to strip the
error explanation in release builds and was changed in a recent
refactoring.
This commit restores the old behaviour (fixing release builds).
Removes the custom code for VS2012 support in config.h,
and reduces diff with upstream config.h.
We still have many custom defines for ARM optimizations
which we probably don't use properly, since we don't
compile the included asm code, so a thorough review and
cleanup would be welcome.
