Use surfman instead of glutin

[jdm]

I have a branch that converts all of the examples to rely on surfman instead of glutin in https://github.com/jdm/webrender/tree/surfman. Is this something that would be desirable?

What's the motivation here? What advantages/disadvantages do you see?

[jdm]

Perhaps rather than replacing the examples, it would be more useful to add one or two examples that demonstrate surfman integration. That would allow people interested in making use of webrender and surfman to have a simple model to follow, rather than having to read the entrails of Servo's complex setup.

It helps a lot, thanks

@jdm Is there a plan to ship more concrete docs? I found some api lack of description, or maybe I should learn some obvious concepts ==
