- with-mesh MESH THUNKprocedure
Calls THUNK with the VBO of the MESH’s vertex buffer bound. If the mesh has been modified by mesh-vertex-set!, the vertex buffer’s data will be updated before the VBO is unbound. When the usage hint given to mesh-make-vao! is dynamic, buffer-sub-data will be used to update the buffer data. When the usage hint is stream, buffer-data will be used.
