move glsequence into "alg" comonent

move glsequence into "alg" comonent
decided to try to make the opengl rendering code toolkit independent
this makes it easier to test some of these components as then I can
just use boost.unittest to verify them.

Also when I python wrap parts it might make sense for the gl components
to be the part that ends up getting exported as the python package.

this is actually a hacked version of the original patch that moves
the test directory a file at a time.
