26.09.2020

+ 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
