Bump the femtovg dependency to ensure we get the fix for error detection on the renderer side
and handle it in the GL backend side by rendering text to the 2D canvas, followed by a panic.
This was moved up to before the resize handler can be installed, as that would end up
clearing the canvas when resizing.
A message on the 2D canvas was chose over an alert message box, as the latter
is rather intrusive and would be a nightmare if many of them popped up
when viewing our docs with a browser
configured that way.
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.
