Detailed Description
File reader for image formats (PNG, JPG, BMP, TGA, etc.)
Uses STB Image library for decoding. Supports:
- PNG, JPG, BMP, TGA, PSD, GIF, HDR, PIC, PNM
- Automatic format detection
- Channel conversion (force RGBA, etc.)
- Direct GPU texture creation
Implements the FileReader interface for consistency with other readers.
