/**
* @brief Atlas-based rendering system for efficient graphics operations
*
*
* The AtlasRenderer class provides efficient rendering by combining multiple
* graphics elements into a single texture atlas, reducing draw calls and
* improving performance for ROM hacking workflows.
*
*
* Key Features:
* - Single draw call for multiple tiles/graphics
* - Automatic atlas management and packing
* - Dynamic atlas resizing and reorganization
* - UV coordinate mapping for efficient rendering
* - Memory-efficient texture management
*
*
* Performance Optimizations:
* - Reduces draw calls from N to 1 for multiple elements
* - Minimizes GPU state changes
* - Efficient texture packing algorithm
* - Automatic atlas defragmentation
*
*
* ROM Hacking Specific:
* - Optimized for SNES tile rendering (8x8, 16x16)
* - Support for graphics sheet atlasing
