graphics_thread_loop()

void MayaFlux::Core::GraphicsSubsystem::graphics_thread_loop ( )

private

Graphics thread main loop.

Self-driven frame processing:

1. Tick frame clock (advances based on wall-clock time)
2. Process visual nodes (VISUAL_RATE nodes)
3. Process graphics buffers (GRAPHICS_BACKEND buffers)
4. Tick scheduler coroutines (FRAME_ACCURATE tasks)
5. Record/submit Vulkan commands or OpenGL draw calls
6. Wait for next frame (vsync timing)
