OpenTK normally uses reflection to load bindings, instead of generating
huge constructors. Although reflection is faster on first load (thanks
to reduced JIT overhead), it fails to work correctly with monolinker.
This branch explores the performance of a direct binding.
We should only generate delegates for actual OpenGL entry points, not
for overloaded functions that resolve to the same entry point. This
improves loading speeds and reduces the size of the compiled dll.
