I'm new to OpenGL ES but I've experience in writing drivers for Windows OS.
My next assignement is to write OpenGL ES 2.0 driver for one of the GPU on windows.
can any one provide info on what technical knowledge i should know like:
1) do i need to implement EGL specs or can i reuse windows WGL?
2) do i need to implement OpenGL Shader Language?
3) what will be the probable driver stack?
4) how do I test?
4) any reference for getting started on driver development?

Thanks in advance.
