 The Windows entrypoint now delegates generic OpenGL error-code/info-string
 tokens and WGL core-context/pixel-format attribute catalogs to `pp_renderer_gl`.
+The headless OpenGL command planner now consumes `pp_renderer_api` recorded

+blend/depth/sampler state, texture formats, primitive modes, draw counts, and

 The existing renderer classes are not yet fully
 behind the renderer interfaces.
