The C# analog of CreatureMode::Render: draws one re-dressed player clone
into a private FBO (RGBA8 + depth24-stencil8) with the fixed DollCamera +
one distant light (retail 0.3,1.9,0.65 @ 2.0), sealed in a GLStateScope so
it can't disturb world/UI GL state. frustum:null ⇒ the doll's synthetic
landblock is always visible ⇒ walked from entry.Entities and drawn from its
current MeshRefs (static pose; idle animation is a later slice).
Manages the FBO directly via GL (ManagedGLFramebuffer is unused/bitrotted
WB infra). UiViewport blit flips V (FBO bottom-left origin vs UI top-left)
so the doll isn't upside-down. Not yet wired — GameWindow hook is next.
