Summary

Adds UI support for KHR_materials_retroreflection, implemented in the companion renderer PR KhronosGroup/glTF-Sample-Renderer#50 (please review/merge that one first).

  • Adds a "Retroreflection" toggle switch and "Retroreflection Strength" debug output channel in Advanced Controls, following the same pattern as the other KHR_materials_* extension toggles.
  • Bumps the glTF-Sample-Renderer submodule to the commit implementing the extension.

Closes #664.

Test plan

  • npm run build succeeds
  • Loaded the glTF-Sample-Assets#285 traffic cone test asset — "Retroreflection" toggle and "Retroreflection Strength" debug channel appear and work correctly in Advanced Controls

Adds a "Retroreflection" toggle switch and "Retroreflection Strength"
debug output channel in Advanced Controls, following the same pattern as
the other KHR_materials_* extension toggles. Bumps the glTF-Sample-Renderer
submodule to the commit implementing the extension.
