Can't set long arrays or arrays of arrays in Shaders

[bil-bas]

Although you can pass vec2/3/4 (or integer or boolean arrays up to size 4) you can't pass longer arrays in.
Can't pass arrays of arrays in (such as an array of vec2/3/4).

Actually, it is possible to set those; and making Ray able to set them from an array would make parsing of arguments much more complicated. We can simply do this instead:

shader["foo[0]"] = 3

0.upto(10) do |i|
  shader["attribute[#{i}]"] = [0, 1, 2]
end
