Misc bug fixes

- Enabled zooming on Surface C++ api
- User modified gradient takes effect
- Scene pointer is updated to selection pointer
- Font changing is listened on selection pointer and label's are generated
  using selected font
- Selection label format copied from scatter. Looks to be very handy.
- Check for OpenGL 1.5 version and block coarse surface if below
- Added some theme handling. Not sure if the bug is fully fixed. Probably
  requires shadow fixes to be fully similar to others.
- HAHAA. Now even single rows and columns supported. Even one value will
  produce surface
