If the gpu-driver does not support OpenGL 3.0 or higher, the app just shows a black screen.

To do: Either give an error message, or rewrite the shader coder to be compatible with OpenGL ES specification.

Qt uses the current debug directory as base path. Since the files inside the shader folder are read by the App on runtime, the folder needs to be copied into this dir.

Every shape stores its own vertices data in memory and has its own memory allocated on the gpu. Also, in the shapes draw function, we activate and deactivate the shader for every single shape.

To do: Make a class Shape Manager which stores the vertex data for shape templates only once, and give each shape instance access to this data, so the same data is only stored in memory once,

Point lights seem to eat too much performance. With about 20 lights on, the app lags heavily.
