D3D GUI Interface

Currently, I'm developing a GUI editor in C++ using DirectX, and I've created a couple of classes some people may find useful. Soon, I will be releasing the whole project, but at the moment, you may find these objects I've created useful. I'm not going to bother explaining it until I've completed the GUI editor, when I do finish it though, there will be an indepth description of all the methods and how to use the GUIEditer to compile GUIs and how to use the GUIReader library(which I will be creating) that you can use to read and display the GUIs created with the GUIEditor. Please note the below code isn't finished nor cleaned up. There are some parts were I was really lazzy and defined variabled that are constant over and over in the Render methods.
