// Campaign V slice V4c: a null Color.Target means "whatever the frame

// not rebind. GpuPassDescription's own remarks say the transitional
// path keeps "clears and framebuffer management" with the spine, and
// forcing 0 here breaks that: PrivateEntityViewportRenderer binds its
// offscreen FBO and then calls WbDrawDispatcher.Draw (see that file's
// RenderToTexture), as does PortalTunnelPresentation. Once the
// dispatcher records through an encoder, binding 0 on BeginPass would
// redirect the paperdoll and creature-appraisal viewports to the
// backbuffer and leave their textures empty — and the offline pixel
// gate does not cover those viewports, so it would have shipped
// silently. This is the same class of fix as the ambient-capability
// save/restore in GlGpuPassEncoder (plan §7.1 rule 1): while raw-GL
// renderers still own framebuffers, the backend preserves what they
// bound rather than asserting its own. Removed at V4h, when the spine
// declares real passes and a target is always explicit.
