Hey all!

I’m glad to announce the third alpha of this project. Releases are available here:

- Windows x64: [https://dump.amyspark.me/krita-4.3.1-alpha-0b32800992-x86\_64.zip](https://dump.amyspark.me/krita-4.3.1-alpha-0b32800992-x86_64.zip)
- Linux x64: [https://dump.amyspark.me/krita-4.3.1-alpha-0b32800-x86\_64.appimage](https://dump.amyspark.me/krita-4.3.1-alpha-0b32800-x86_64.appimage)

```

In this release, I fixed the following issues:

- SeExpr textures use the scRGB color space, which is not supported by Qt’s `QColor` until 5.12. This makes the conversion to Krita space unbearably slow (thanks @wolthera )
- Refactored SeExpr error reporting to make messages Qt-translatable.
  - **This adds KDE’s ECM to the list of (optional) dependencies of SeExpr.**

- Error reporting is now available, including highlighting! (thanks @wolthera too for noticing)
- Configuration is saved and restored when changing between Fill layer types ([bug 422885](https://bugs.kde.org/show_bug.cgi?id=422885), thanks @halla )
- Cleaned up SeExpr headers
  - They are now installed only if used in the UI library itself.

- UI labels have extra spacing (thanks Wolthera van Hövell)

Another outstanding issue is SeExpr’s vulnerability to the current `LC_NUMERIC`  
locale, due to its use of `sscanf` and `atof`. I am sad to announce I won’t be  
able to change this; the library I wanted to use, [scn](https://github.com/eliaskosunen/scnlib) is [itself vulnerable](https://github.com/eliaskosunen/scnlib/issues/24) to locale changes.

But the most important feature, and final contribution, are **bundleable presets**!

This enables SeExpr scripts to be bundled just like any other resource in Krita.  
Below you can find a bundle containing all of [the example scripts](https://krita-artists.org/t/procedural-texture-generator-example-and-wishes/7638/8) posted by @wolthera .
