+ Added BoundingBoxes to Meshes + SM.Base.Objects.Mesh + Vertex Colors + ShowItem Collections + 2D Equlivant + Default Class to store Default Values + SM.OGL.GLSystem to store OpenGL specific system information + SM2D.DrawColor // not working yet + SM2D.DrawComplex to allow access to all features. + SM2D.DrawPolygon + Polygon system // for 2D only yet ~ Renamed SM.OGL.Mesh to SM.OGL.GenericMesh
