TexturePacker for Mac

Features

• New GameMaker data format that can be loaded with texturegroup_add() without a loader script.
• The existing GameMaker format is now called "GameMaker (loader script)".
• Match the native look of Windows 11 and macOS 27 with the modern system styles.

Fixes

• Sprite sheet splitter: sheets of solid tiles without transparency no longer lose a column to the background heuristic. The background color is only removed when the corners agree on it, and it is removed everywhere on the sheet, including pockets inside a sprite such as the space between a character's legs. The new Remove solid background checkbox below the algorithm tabs controls what the preview shows and what the saved sprites contain: switch it off to keep the background, or for tiles that happen to share a corner color. Formats without transparency such as JPEG always keep the background.
• Start on Ubuntu 26 — the Debian package now pulls in the xcb/xkb runtime libraries the app needs.
• Unreal Paper2D no longer warns about a TexturePacker prefix mismatch on every import.
• Japanese and Chinese: Latin words and numbers are now separated from CJK text by a space throughout the interface.
• Missing AVX2 support: loading or exporting ASTC textures now reports an error instead of crashing.
