We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.
There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.
Happy new year to the wonderful Godot community!
2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.
We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)
Here's to a great year 2021 for all Godot users 🎆
We haven't had a proper implementation for COMPRESS_PVRTC2 (which is PVRTC1 2-bpp) in years,
so let's drop it instead of keeping a compress type which doesn't work.
The other enum values were renamed to clarify that our PVRTC2 and PVRTC4 are respectively
PVRTC1 2-bpp and PVRTC1 4-bpp. PVRTC2 2-bpp and 4-bpp are not implemented yet.
The code we had for PVRTexTool doesn't work as it's not compatible with current
PVRTexTool CLI options, and likely hasn't been for years.
Instead, we have our own vendored pvrtccompressor thirdparty library which all
users have thus de-facto been using. This commit moves the compress code to
`modules/pvr` where it belongs.
There's no proper compress function for PVRTC 2-bit format, that's a bug that
will need to be fixed (currently it's compressed as 4-bit format even if you
use Image::FORMAT_PVRTC2).
Fixes#28669.
