Have got text rendering on the hud now. from a font texture - basic stuff, but can now advance with hud fully.

Much of it, was just cut and past from my C++ code replacing, glTexCoord2f with GL.TextureCoord2 stuff like that. same logic.

Think it will take a week to port the LUA driven multi-hudmode logic to c# if memory serves, its landing, navigation, bombing, guns, air to air, and air to ground. The GR3 harrier not having radar, had the pilot manually guessing what the wingspan and range was to the target, so modifying the gun aim with rotational movement.
