Hardware instancing problem with Panda 1.8

You might need to do something like

        for i in range(4):
            col = soldiertrans.getCol(i)
            shader_data.append(UnalignedLVecBase4f(col[0], col[1], col[2], col[3]))

because getCol alone will just give a regular vec4.

I have some code that I should be able to extract out of my game that I think will be helpful, I can probably find some time tonight to have a look.
