We currently only support access chains that end in a matrix by propagating
"needs transpose" flag upstream which flips the matrix multiplication order.
It's possible to support indexed extraction as well, however it would have to
generate code like this:
vec4 row = vec4(UBO[0].y, UBO[1].y, UBO[2].y, UBO[3].y);
for a column equivalent of:
vec4 row = UBO[1];
It is definitely possible to do so but it requires signaling the vector output
that it needs to switch to per-component extraction which is a bit more trouble
than this is worth for now.
