Changelog

• Download any gallery spritesheet as a PNG, rendered at full resolution from the original sprites rather than the preview image
• Download a gallery spritesheet as a ZIP containing the sheet, every frame as a separate PNG, and the project JSON

• Force a packed atlas to any exact size instead of the power-of-2 size the packer picks, so you decide the canvas
• Sprites that no longer fit a forced size are counted in a warning on the canvas instead of the atlas quietly growing
• Drag packed sprites around the canvas to place them by hand, with Reset Layout to go back to the packer's arrangement
• The "% packed" badge now measures against the real exported atlas size, so wasted space is easier to spot

• Name your animation when exporting Sparrow / Starling XML, so frames come out as idle0000, idle0001 and so on. Friday Night Funkin and Starling key animations off these names
• XML export now records trimmed frame offsets (frameX, frameY, frameWidth, frameHeight)
• Atlas import reads Sparrow XML and Cocos2d .plist alongside TexturePacker JSON, so Geometry Dash sheets slice from their own metadata
• Rotated frames in an atlas are turned back the right way up on import

• Replace the blog with a Guides section at /guides, organised by topic and skill level
• Bug fixes

• Import packed atlases: choose "Atlas" in the importer and attach the atlas JSON to slice sprites back out in packed order
