for now to some 'special' cases where we can do a direct mapping between D3D
types and GL types.

Note: in the future all calls will go through vertex arrays but the arrays
will be generated by this function.
Note2: colours cannot be mapped directly because they are stored as BGRA in memory
(ie not as an array of R, G, B, A as OpenGL does it but as a LWORD 0xAARRGGBB
which, as we are little indian, gives a B, G, R, A storage in memory.
