2067 * is the number of entries in the array multiplied by the number of slots
2068 * consumed by a single element of the array.
2070 * The spec says nothing about how structs are counted, because vertex
2071 * attributes are not allowed to be (or contain) structs. However, Mesa
2072 * allows varying structs, the number of varying slots taken up by a
2073 * varying struct is simply equal to the sum of the number of slots taken
2074 * up by each element.
2076 * Doubles are counted different depending on whether they are vertex
2077 * inputs or everything else. Vertex inputs from ARB_vertex_attrib_64bit
