The last remaining ERR_EXPLAIN call is in FreeType code and makes sense as is
(conditionally defines the error message).
There are a few ERR_EXPLAINC calls for C-strings where String is not included
which can stay as is to avoid adding additional _MSGC macros just for that.
Part of #31244.
Condensed some if and ERR statements. Added dots to end of error messages
Couldn't figure out EXPLAINC. These files gave me trouble: core/error_macros.h, core/io/file_access_buffered_fa.h (where is it?),
core/os/memory.cpp,
drivers/png/png_driver_common.cpp,
drivers/xaudio2/audio_driver_xaudio2.cpp (where is it?)
Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.
To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.
If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.
Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.
It's not necessary, but the vast majority of calls of error macros
do have an ending semicolon, so it's best to be consistent.
Most WARN_DEPRECATED calls did *not* have a semicolon, but there's
no reason for them to be treated differently.
It seems to stay compatible with formatting done by clang-format 6.0 and 7.0,
so contributors can keep using those versions for now (they will not undo those
changes).
-Added fade out frames constant at top of file, defining how many frames should have fade out applied (to avoid pops at the end of trim)
-Rewrote parts of the trimming logic to use an average of volume across all channels instead of any particular channel
-Added fade-out to trimming
Existing code only did the reparenting when the parent node was a bone. This
change fixes that, plus the reparenting code itself, which used the index of
the skin instead of the skin index itself to address the skeleton array.
To follow the glTF 2.0 specification in all cases (including outside
of imported glTF scenes), the blue channel is now used for metallic
and the green channel is now used for roughness.
We could already choose a script global class for root_type at scene import config. However, it would fall back to default Spatial if a script global class is chosen. This will make sure the base type for the script class is used, and the script to root node is attached upon import.
This fixes https://github.com/godotengine/godot/issues/20377 , where blend shape scales the mesh if the mesh is also skinned.
The issue was that the blend shape was trying to blend using BLEND_SHAPE_MODE_RELATIVE (directly adding everything in morph shape as displacement), while bone weights were copied in the morph shape, which resulted in 2x bone weights causing mesh to become bigger when blended.
Setting the blend mode to BLEND_SHAPE_MODE_NORMALIZED while guaranteeing the data is correct fixes the issue (previously treating gltf2's morph displacement data as blend target data). Ideally we still want to use BLEND_SHAPE_MODE_RELATIVE since it may need much less data, but that seems to require a larger refactor?

This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
