anx.framework/ANX.Framework.Windows.GL3/GraphicsDeviceWindowsGL3.cs
Glatzemann f06890de59 reading used GraphicsProfile out of game assembly
some work on Kinect InputSystem (Dispose, fetching of RGB image)
changed handling of native textures (providing data for Texture2D at the moment)
implemented SetData methods for Texture2D
basic Dispose handling of Texture and Texture2D implemented
RenderSystemDX10: moved FormatSize method to FormatConverter to avoid duplicated code
RenderSystemGL3 is BROKEN in this version. New texture handling needs to be adapted.
