Knowing whether a widget is being interacted with allows to implement
bi-directional updates without feedbacks.

Previously, the keyboard is open by default, even without any focus.
Now, the keyboard will remain closed, until `.focus()` is called. That
change also prevents the keyboard from reopening immediately after blur.

This CL introduces 2 new path builders:
- Outline which takes a PathSpec to be outlined
- Stroke which takes a PathSpec and a stroke style, to stroke a path.
typically, code like this:
var p clip.Path
...
p.Outline().Add(o)
should be replaced with:
var p clip.Path
...
clip.Outline{Path: p.End()}.Op().Add(o)
similarly, stroking should be modified from:
var p clip.Path
...
p.Stroke(width, clip.StrokeStyle{...}).Add(o)
to:
var p clip.Path
...
clip.Stroke{Path: p.End(), Style: clip.StrokeStyle{Width:...}}.Op().Add(o)
here are tentative 'rf' scripts (see rsc.io/rf for more details):
```
ex {
import "gioui.org/op";
import "gioui.org/op/clip";
var p clip.Path;
var o *op.Ops;
p.Outline().Add(o) -> clip.Outline{Path:p.End()}.Op().Add(o);
}
ex {
import "gioui.org/op";
import "gioui.org/op/clip";
var o *op.Ops;
var p clip.Path;
var sty clip.StrokeStyle;
var width float32;
p.Stroke(width, sty).Add(o) -> \
clip.Stroke{ \
Path:p.End(), \
Style: clip.StrokeStyle{ \
Width: width, \
}}.Op().Add(o);
}
```

The example module is moving to git.sr.ht/~eliasnaur/gio-example.
We still need some main package for testing gogio, so update reference
to use the module path (gioui.org/example).

This introduces a new material.Palette type that captures the color information
necessary to render a widget. This type is embedded in the material.Theme to
make it easier to swap to a different palette for part of the UI by reassinging
the Palette field.

Previously, the only way to manipulate the clipboard (read or write) is
using the `app.Window`.
The new `clipboard.ReadOp` and `clipboard.WriteOp`makes possible to
read/write from the widget.

As a consequence, most API is gone from gpu/gl, and embedding Gio in
foreign frameworks don't need to provide an OpenGL implementation.
The next change simplifies the GLFW embedding example accordingly.

The existing implementation cannot remove the focus of some widget,
doesn't have an option to focus without display the on-screen keyboard
and it automatically focuses the first InputOp, aggressively.
That change aims to make possible: remove focus from any widget. Add
focus without displaying the on-screen-keyboard/soft keyboard. Don't
automatically focus any widget. Don't recover focus when the widget is
visible again.
Fixes gio#180.

A previous change converted the package argument to gogio to an absolute path.
However, gogio supports all package paths that may appear in Go import statements.
For example, the path "gioui.org/cmd/example/kitchen" should not be converted.

Currently this comes up with RRect/Border that has zero corners. It
improves them from ~250ns to ~170ns. While it's possible to check this
in RRect implementation, however it'll slow down calls with non-zero
corners.
