GLES 2.0 rendering path implemented and working (sort of):
- restructured GLES 1.0 rendering path code to be the same layout as used for GLES 2.0
- still a few bugs to fix in GLES 2.0 rendering:
  1. Desktop shows thru on gears - maybe shader problem? kind of looks cool, its a new feature :)
  2. Light is comming from wrong direction compared to GLES 1.0 render
