Rewrote and refactored creation of dummy window and OpenGL context on

Windows to be encapsulated in WindowsDummyGLDrawable class. This is a
prerequisite for implementing top-level pbuffer support in the
GLDrawableFactory (i.e., not associated with a GLCanvas). Refactored
context implementations further on all platforms.
