cc #215
Handle Input event from the input directly instead of going through winit
for the TextInput.
Note that this doesn't handle the composition event well, so the text is
only considered written when it is accepted
Delegate the decision how to implement the Clip element entirely into the backend,
where the GL backend can now explicitly render
children into a layer, instead of the hack with a layer in the renderer's
state and the extra save/restore pair.
The README.md contains the warning that used to be in lib.rs.
Add README.md files to all internal crates
... pointing to the official public crate to use instead.

This API allows specifying a callback that will be invoked when setting
up graphics (great for compiling shaders), before rendering a frame (but
after the clearning of the surface background), after rendering a frame
(before swapbuffers) and when releasing graphics resources.
