IFAKA bf3f270067 fix: add NULL checks for frameBuffer in GfxRenderer (#79) ... ## Problem `invertScreen()`, `storeBwBuffer()`, and `restoreBwBuffer()` dereference `frameBuffer` without NULL validation. If the display isn't initialized, these functions will crash. ## Fix Add NULL checks before using `frameBuffer` in all three functions. Follows the existing pattern from `drawPixel()` (line 11) which already validates the pointer. Changed `lib/GfxRenderer/GfxRenderer.cpp`. ## Test - Follows existing validated pattern from `drawPixel()` - No logic changes - only adds early return on NULL - Manual device testing appreciated		2025-12-21 13:34:58 +11:00
