SDL3FrameManager Class

Manages frame lifecycle including command buffers, swapchain acquisition, and presentation.

internal sealed class SDL3FrameManager : System.IDisposable

Inheritance System.Object → SDL3FrameManager

Implements System.IDisposable

Methods
BeginFrame()	Begin a new frame by acquiring command buffer and swapchain texture. Waits for the oldest in-flight fence first to guarantee the corresponding swapchain image and transfer buffer have been released by the GPU.
EndFrame()	End the current frame and submit the command buffer. The fence is stored for the next BeginFrame() call to wait on, bounding the CPU to at most Brine2D.Rendering.SDL3FrameManager.MaxInFlightFrames frames ahead of the GPU.
ReleaseInFlightFences()	Releases any fence handles still held in the in-flight circular buffer. Call this after SDL3.SDL.WaitForGPUIdle(System.IntPtr) at shutdown so all fences are already signaled before releasing them.
