Remove clipboard functionality and enhance performance monitoring features
- Deleted clipboard-related files (clipboard.cc, clipboard.h, clipboard.mm) to streamline the codebase. - Added a performance dashboard in the EditorManager to monitor performance metrics and improve user experience. - Integrated performance monitoring capabilities across various editors, allowing for detailed timing of critical operations. - Updated the graphics system with batch processing for texture updates, significantly improving rendering performance. - Introduced a memory pool allocator for efficient memory management during graphics operations.

* The AtlasRenderer class provides efficient rendering by combining multiple

|

* 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
|
||||
* - Efficient palette management across atlas
|

* - Tile-based UV coordinate system

* @brief High-performance memory pool allocator for graphics data

|

* The MemoryPool class provides efficient memory management for graphics operations
|
||||
* in the YAZE ROM hacking editor. It reduces memory fragmentation and allocation
|
||||
* overhead through pre-allocated memory blocks.
|
||||
*
|
||||
* Key Features:
|
||||
* - Pre-allocated memory blocks for common graphics sizes
|
||||
* - O(1) allocation and deallocation
|
||||
* - Automatic block size management
|
||||
* - Memory usage tracking and statistics
|
||||
* - Thread-safe operations
|
||||
*
|
||||
* Performance Optimizations:
|
||||
* - Eliminates malloc/free overhead for graphics data
|
||||
* - Reduces memory fragmentation
|
||||
* - Fast allocation for common sizes (8x8, 16x16, 32x32 tiles)
|
||||
* - Automatic block reuse and recycling
|
||||
*
|
||||
* ROM Hacking Specific:
|
||||
* - Optimized for SNES tile sizes (8x8, 16x16)
|
||||
* - Support for graphics sheet buffers (128x128, 256x256)
|
||||
* - Efficient palette data allocation
|
||||
* - Tile cache memory management

*
|
||||
* The PerformanceDashboard provides real-time monitoring and analysis of graphics
|
||||
* performance in the YAZE ROM hacking editor. It displays key metrics, optimization
|
||||
* status, and provides recommendations for performance improvements.
|
||||
*
|
||||
* Key Features:
|
||||
* - Real-time performance metrics display
|
||||
* - Optimization status monitoring
|
||||
* - Memory usage tracking
|
||||
* - Frame rate analysis
|
||||
* - Performance regression detection
|
||||
* - Optimization recommendations
|
||||
*
|
||||
* Performance Metrics:
|
||||
* - Operation timing statistics
|
||||
* - Memory allocation patterns
|
||||
* - Cache hit/miss ratios
|
||||
* - Texture update efficiency
|
||||
* - Batch operation effectiveness
|
||||
*
|
||||
* ROM Hacking Specific:
|
||||
* - Graphics editing performance analysis
|
||||
* - Palette operation efficiency
|
||||
* - Tile rendering performance
|
||||
* - Graphics sheet loading times
