Add BPP format management and optimization features
- Introduced BPPFormatManager for handling various bitmap formats (2BPP, 3BPP, 4BPP, 8BPP) with conversion capabilities. - Enhanced AtlasRenderer to support bitmap addition with BPP format optimization and added methods for optimized rendering. - Implemented GraphicsOptimizer for analyzing and optimizing graphics sheets based on BPP formats, including memory and performance considerations. - Developed BppFormatUI for user interface interactions related to BPP format selection and conversion previews. - Integrated BPP format management into the canvas system, allowing for format selection and conversion within the GUI. - Updated CMake configuration to include new source files related to BPP management and optimization.

* - Multi-format BPP support (2BPP, 3BPP, 4BPP, 8BPP)
|
||||
* - Intelligent format detection and analysis
|
||||
* - High-performance format conversion with caching
|

* - Palette depth analysis and optimization
|
||||
* - Memory-efficient conversion algorithms
|
||||
*
|
||||
* Performance Optimizations:
|
||||
* - Cached conversion results to avoid redundant processing
|
||||
* - SIMD-optimized conversion algorithms where possible
|
||||
* - Lazy evaluation for expensive analysis operations
|
||||
* - Memory pool integration for efficient temporary allocations
|

*
|
||||
* The GraphicsOptimizer provides intelligent optimization of graphics data
|
||||
* for Link to the Past ROM hacking workflows, balancing memory usage,
|
||||
* performance, and visual quality.
|
||||
*
|
||||
* Key Features:
|
||||
* - Intelligent BPP format optimization based on actual color usage
|
||||
* - Graphics sheet analysis and conversion recommendations
|
||||
* - Memory usage optimization with quality preservation
|
||||
* - Performance optimization through atlas rendering
|
||||
* - Batch processing for multiple graphics sheets
|
||||
* - Quality analysis and loss estimation
|
||||
*
|
||||
* Optimization Strategies:
|
||||
* - Memory Optimized: Minimize ROM size by using optimal BPP formats
|
||||
* - Performance Optimized: Maximize rendering speed through atlas optimization
|
||||
* - Quality Optimized: Preserve visual fidelity while optimizing
|
||||
* - Balanced: Optimal balance of memory, performance, and quality
|
||||
*
|
||||
* ROM Hacking Specific:
|
||||
* - SNES-specific optimization patterns
|
||||
* - Graphics sheet format analysis and conversion tracking
|
||||
* - Palette optimization based on actual usage
|
||||
* - Integration with existing YAZE graphics pipeline
