Slic3r/src/slic3r/GUI/GLToolbar.cpp
Enrico Turri d87b478d60 Camera refactoring 
1) All camera related OpenGL calls moved into class

2) The Camera class now stores the view matrix, the projection matrix and the viewport

3) The Camera class now exposes methods to get the camera orientation vectors, the camera position, the view matrix, the projection matrix and the viewport

4) All the code operating on the camera or requiring camera data has been modified to use the new methods
