Setting constant vertex attributes with glDrawArrays() doesn't work right
because the last attribute isn't copied to ctx->Current. Typically,
only the last attribute doesn't get set, since vbo_exec_wrap_upgrade_vertex()
ends up getting called when setting a new attribute, and it will copy all
previously set attributes to Current.

I'm not too familiar with this code, so I'd appreciate if somebody who
knows the vbo code better could take a quick look.
