Remove the custom GL post-process (ViewportColorCorrector) that bypassed
HdxColorCorrectionTask. Instead pass colorCorrectionMode, ocioDisplay,
ocioView, ocioColorSpace, and ocioLook directly to UsdImagingGLRenderParams
and SetColorCorrectionSettings(), delegating correction to Hydra —
the same approach used in usdview's stageView.renderSinglePass().

Document the decision to replace HdxColorCorrectionTask with a custom GL
post-process (linear render + sRGB/OCIO correction via the OCIO GPU API),
including rationale, pipeline, consequences, and alternatives considered.
