*
* @brief Renders the quad. Note! THis should be called *after* all 3D drawing (i.e. after postDraw3D()), but *before* draw2D()
* The steps are as follows:
* First bind the PBO as the pack buffer, then read the pixels directly to the PBO and unbind
* Next bind the PBO as the unpack buffer, then push the pixels straight into the texture
* Setup texture unit for the render surface
* switch to the GL_TEXTURE* value that we are using as our screen texture holder
* write the pixels
* unbind
* Draw full screen quad with screen textures, calling setupScreenRenderProg() to access the chaders for the effect desired.
