Import: Cleanup and optimize etcpak compression method
Avoid unnecessary allocation of temporary buffers for each mip, and creates
only one Image with the compressed data.
Also renames variable and reorders code for clarity.

Clarify that squish is now only used for decompression.

Documented which formats can be decompressed in Image.

Third party libraries

Please keep categories (## level) listed alphabetically and matching their respective folder names. Use two empty lines to separate categories for readability.

basis_universal

Files extracted from upstream source:

  • .cpp and .h files in root folder except for basisu_tool.cpp (contains main and can cause link error)
  • .cpp, .h and .inc files in transcoder/, keeping folder structure
  • LICENSE

bullet

Files extracted from upstream source:

  • src/* apart from CMakeLists.txt and premake4.lua files
  • LICENSE.txt

certs

File extracted from a recent Fedora install: /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem (It can't be extracted directly from the package, as it's generated on the user's system.)

cvtt

Files extracted from upstream source:

  • all .cpp, .h, and .txt files in ConvectionKernels/

doctest

Extracted from .zip provided. Extracted license and header only.

enet

  • Upstream: http://enet.bespin.org
  • Version: 1.3.17 (e0e7045b7e056b454b5093cb34df49dc4cee0bee, 2020)
  • License: MIT

Files extracted from upstream source:

  • all .c files in the main directory (except unix.c win32.c)
  • the include/enet/ folder as enet/ (except unix.h win32.h)
  • LICENSE file

Important: enet.h, host.c, protocol.c have been slightly modified to be usable by Godot's socket implementation and allow IPv6 and DTLS. Apply the patches in the patches/ folder when syncing on newer upstream commits.

Three files (godot.cpp, enet/godot.h, enet/godot_ext.h) have been added to provide enet socket implementation using Godot classes.

It is still possible to build against a system wide ENet but doing so will limit its functionality to IPv4 only.

etcpak

Files extracted from upstream source:

  • Only the files relevant for compression (i.e. Process*.cpp and their deps):
    Dither.{cpp,hpp} ForceInline.hpp Math.hpp ProcessCommon.hpp ProcessRGB.{cpp,hpp}
