    draw: No need to rebase for elt_bias.
    
    As we are rebasing to min_index + elt_bias, and the vertex buffer has no
    elt_bias.
    
    I still don't know how to exercise this code. I hope this is now right.

    gallium/docs: Make it clear that minIndex, maxIndex is exclusively a index buffer characteristic.
    
    Unlike the indexBias which is specific to a draw call.
    
    This are the semantics of both D3D and GL ARB_draw_elements_base_vertex
    extension.

    gallium: Add index bias parameter to draw_elements and friends.
    
    indexBias corresponds to:
    - BaseVertexIndex parameter of D3D9's
      IDirect3DDevice9::DrawIndexedPrimitive method
    - BaseVertexLocation parameter of ID3D10Device::DrawIndexed
    
    Although a positive indexBias can be easily be implemented in Gallium by
    adding indexBias*stride to each vertex buffer base offset, a negative
    indexBias cannot, as the final vertex buffer offset could be negative.
    
    I'm not aware of this functionality being exposed to GL drivers, so for
    now all hardware drivers will just assert(indexBias == 0).
