Performance

• SKTypeface caching — shared static cache with reference counting, avoids reloading fonts per component
• SKSurface reuse — surfaces are reused when size and format match, only recreated when dimensions change
• FontMapper caching — FontMapper objects reused when typeface hasn't changed
• Pixmap-only disposal — only pixmap is disposed between renders, surface kept for reuse
• Reduced per-render allocations — cached objects avoid GC pressure during text rendering
