This applies our existing style guide, and adds a new rule to that style
guide for modular components such as platform ports and modules:
Includes from the platform port or module should be included with relative
paths (relative to the root folder of the modular component, e.g.
`platform/linuxbsd/`), in their own section before Godot's "core" includes.
The `api` and `export` subfolders also need to be handled as self-contained
(and thus use relative paths for their "local" includes) as they are all
compiled for each editor platform, without necessarily having the api/export
matching platform folder in the include path.
E.g. the Linux editor build will compile `platform/android/{api,export}/*.cpp`
and those need to use relative includes for it to work.
Adds a new OS::get_system_ca_certs method which can be implemented by
platforms to retrieve the list of trusted CA certificates using OS
specific APIs.
The function should return the certificates in PEM format, and is
currently implemented for Windows/macOS/LinuxBSD(*)/Android.
mbedTLS will fall back to bundled certificates when the OS returns no
certificates.
(*) LinuxBSD does not have a standardized certificates store location.
The current implementation will test for common locations and may
return an empty string on some distributions (falling back to the
bundled certificates).
This quotes the executable name so that copying it always works
(even if the path contains spaces).
The command is also indented from the rest of the text and is
no longer single-quoted, as that can prevent the command from
running if the line is copied in its entirety (with the quotes).
* Only two texture import modes for low/high quality now:
* S3TC/BPTC
* ETC2/ASTC
* Makes sense given this is the general preferred and most compatible combination in most platforms.
* Removed lossy_quality from VRAM texture compression options. It was unused everywhere.
* Added a new "high_quality" option to texture import. When enabled, it uses BPTC/ASTC (BC7/ASTC4x4) instead of S3TC/ETC2 (DXT1-5/ETC2,ETCA).
* Changed MacOS export settings so required texture formats depend on the architecture selected.
This solves the following problems:
* Makes it simpler to import textures as high quality, without having to worry about the specific format used.
* As the editor can now run on platforms such as web, Mac OS with Apple Silicion and Android, it should no longer be assumed that S3TC/BPTC is available by default for it.
