renderer: render scene to a texture
...
And then render the texture onto a quad that fills the screen
The screen-filled quad upon which the texture is rendered must never be rendered in wireframe. Rendering in wireframe only makes sense when rendering the world on the texture

write number of triangles to Chunk only when sending to GPU

previously the current number of vertices was stored in the chunk, and the same variable got later reused for the number of triangles. This modification increases clarity and avoid glitches when blockpicking
