=Embedding a framebuffer window=

The project can be split into two main parts:
*Creating a new Qt framebuffer
*Embedding a framebuffer window

I started by creating a new cross-platform Qt framebuffer which was implemented almost completely until midterm evaluation. More information about my work in this period can be found [http://brlcad.org/wiki/User:Vladbogolin/GSoC2014/Midterm here].

In the second part I worked at embedding a framebuffer window in the existing Qt display manager. Even though I encountered quite a lot of unexpected problems (bad drawings, drawings that disappeared) in the end I managed to successfully embed a framebuffer window. I can say that when I saw correct and permanent drawings made in mged I was really relieved and also really excited.

Apart from this task, I also added support for keyboard and mouse events and for using, reading and writing a colormap to the already implemented framebuffer.

When it comes to the actual code, it can almost all be found in libfb/if_qt.cpp and libdm/dm-qt.cpp. As I predicted in the first part, in order to embed a frambuffer window another 800 lines of code were necessary.

=Results=
As you can see from the below pictures the framebuffer is integrated with the raytracer and it can successfully display raytraced models.

When it comes to embedding a frambuffer window, I tested the behavior in both mged
