FlexRenderer

Render deformable flex surfaces and lines

<MujocoCanvas config={config}>
  <FlexRenderer />
</MujocoCanvas>

Accepts normal R3F group props. Uses flex_elem for indexed 2D triangles and 1D line segments, and flex_shell for the external triangles of 3D flexes. Vertex positions follow data.flexvert_xpos each frame and surface normals are updated. Color and opacity come from flex_rgba. Flex textures and physical thickness visualization are not yet supported. Models without flexes render nothing.
