[Vala] OpenGL definitive binding and samples

["Matías De la Puente" <mfpuente ar gmail com>]

Hi, all

I finally update the OpenGL bindings (gl.vapi and glu.vapi).
The bindings were made in a traditional way (glBegin(GL_TRIANGLES)) because the all the avaible documentation describes the functions like this..
And will be more easy to port opengl source code to vala.

Samples can be found here:
