as far as I know, gmsh is an unstructured mesh generator, so by default 
that generates triangular meshes(in 2D). By 'transfinite' definition 
triangles are combined into quads(I hope this is not wrong, anyway 
developers will comment on that.)

There should be transfinite examples to generate quad meshes in the 
tutorials. Mesh order could be set with the options, I have used this 
before but do not remember now, sth like secondOrder complete, you can 
set that to 1 or 0 depending on the choice, that should be in the manual.
