+ Added Field to DrawingBasis to enfore PrimitiveTypes + LastObject to context for Debugging + AppendRenderbuffer to Framebuffer ~ Added a depthbuffer to RenderPipeline.CreateWindowFramebuffer ~ Proper ZIndices over Z-Translation and DepthBuffer ~ Made "ShaderArguments["LineWidth"]" set the LineWidth even if the object isn't maked as LineMesh ~ Made that the SM2D.PolygonVertex can translate OpenTK.Vector2 by itself. ~ Made the SM2D.Transformation.ZIndex a CVector1 instead a float
