Converted OpenGl tutorials to F#.
- Silk.NET
- 12 out of 13 tutorials (omitted model loading)
- OpenTK
- Chapter 1: all 9 tutorials
- Chapter 2 maybe in the future...
F# features:
- Tried to keep to functional principals (no mutable if not necessary, no classes)
- Result computational-expression
- Units of measure for degrees and radians
