gl: add windows implementation based on ANGLE

ANGLE is an open source project that implements OpenGL ES on top of
DirectX. It is used by Chrome to implement WebGL:

	https://github.com/google/angle

It can be compiled into libGLESv2.dll/libEGL.dll and used directly
from Go. This CL includes the changes necessary to the gl package
to use ANGLE.

For the EGL changes, I intend to get x/exp/shiny/driver/gldriver
working, and then make x/mobile/app use it when compiling for
GOOS=windows. (The dependency on shiny's screen package will only
hold when building for desktop OSs.)

For golang/go#9306

Go support for Mobile devices

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.


Contributions to Go are appreciated. See https://golang.org/doc/contribute.html.
