Fixed a bug with scene view where the render texture would get stretched at smaller sizes

Game window now properly displays main camera contents
Newly added cameras are main by default

  - Will need to ensure the code works in OpenGL (means porting shaders or building the cross compiler). I cannot delay 
    this as later it will be hard to debug when the pipeline is more complex.
