// RenderTargetCache:
// The RenderTargetCache pattern is used in the D3D9, D3D11, Vulkan, and WebGPU back-ends. It is a
// cache of the various back-end objects (RenderTargets) associated with each Framebuffer
// attachment, be they Textures, Renderbuffers, or Surfaces. The cache is updated in Framebuffer's
// syncState method.
