2021-04-13Add `etcpak` library for faster ETC/ETC2/S3TC imports.K. S. Ernest (iFire) Lee
- `etc` module was renamed to `etcpak` and modified to use the new library. - PKM importer is removed in the process, it's obsolete. - Old library `etc2comp` is removed. - S3TC compression no longer done via `squish` (but decompression still is). - Slight modifications to etcpak sources for MinGW compatibility, to fix LLVM `-Wc++11-narrowing` errors, and to allow using vendored or system libpng.

2020-04-01etc2comp: Fix max iterations for RGBA channelsRémi Verschelde
Those checks were *very likely* meant to clamp the max value, not the min one. Fixes https://github.com/godotengine/godot/issues/10059#issuecomment-606993001.

2017-11-05Convert DOS line endings to Unix line endingsRémi Verschelde
Should fix issues some of us have with `misc/dist/uwp_template/AppxManifest.xml` always showing up as modified. Might cause issues on Windows due to the removal of BOMs or change of line endings in some of the Mono, UWP or gradlew.bat files, we will test and adapt if need be.
2017-07-08Revert "Mark where ETC1 restriction needs to be done to speed up RGBA8 import"Rémi Verschelde
This reverts commit 8b362b50094ccd332c6ee3d0853a6b9b49f70253. We should not apply our clang-format style to thirdparty code, it makes it impossible to maintain.
