increased the amount of shared code between vertex and index buffers fixed GraphicsDevice.Reset() which didn't save the provided presentation parameters and the backbuffer was still bound after the recent changes about the rendertargets Vertex and IndexBuffers that get dynamically generated for the UserDraw methods dispose the buffers now Added DebugNames to Index and VertexBuffers and their Dynamic version.
