- Added methods for applying palettes based on metadata, allowing for flexible palette handling in different bitmap types. - Introduced a new BitmapMetadata struct to track source format and palette requirements. - Enhanced ApplyStoredPalette and SetPaletteWithTransparent methods for improved palette application and transparency handling. - Updated SDL surface pixel management with a new UpdateSurfacePixels method for better pixel data handling. Benefits: - Improves the rendering capabilities of the Bitmap class by supporting various palette formats. - Enhances user experience with more intuitive palette management in graphics operations.
