Add ImagePreviewWidget class for previewing texture assets: - TGA image loading (uncompressed and RLE) - Xbox 360 XBTX2D texture format support (work in progress) - DXT1/DXT5 block decompression - Xbox 360 texture untiling using SDK algorithms - Scroll-to-zoom and drag-to-pan functionality - Debug export to PNG for development The Xbox 360 texture decoding is still a work in progress and needs further research for proper implementation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
