tobid7 f87c103d8d # Stage 1.8 
- Renderer now vould use more screen Objects
- Register default Top and Bottom Screens (for Overlays and UI7)
- Make ToHex an Inline header func
- Add GetCompilerVersion
- Add Library Compile And Version Info to common
- Remove z of vertex object and shader in position
- Add Container base and SubContainers to UI7
- Add abillity to Join Multiple Objects in Same Line and Center them
- Fix LayerOrder Bug for updating texts in DrawList
