Similarly to `Vector2` and `Rect2` transforms in 2D and Vector3, Plane,
and AABB in 3D. PoolVector2Array and PoolVector3Array were the only
missing Variant types in both Transform2D and Transform respectively.
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?)
These silently fail, so they should be removed. I accidentally added most of these last year, trying to make everything else consistent with Quat, sorry!
Also, a few tiny nitpicking changes are included, like whitespace and misspellings.
For clarity, assign-to-release idiom for PoolVector::Read/Write
replaced with a function call.
Existing uses replaced (or removed if already handled by scope)
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.
Improved documentation of rsplit Method for String class.
Removed "divisor" (i will also change variants_call.cpp) and added "delimiter" in its place. Also moved the example at the bottom of the description.
The return_type is used by the GDScript parser (and possibly other
scripting languages), so it MUST be initialized at least.
It could be initialized to Variant::NIL in release, but I see no reason
for not setting the actual value.
See similar issue in 95dfa5b .
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.
They were introduced in #14704 but need more discussion IMO,
they don't strike me as core features that would have to be
registered in Variant directly.
Moreover, they currently break the documentation XML as string
constants end up encoded as e.g. `value=""..""`.
