app/internal/glimpl: [wasm] remove slow getError calls

The removal of getError significantly improves performance on js/wasm:

Opera 72 (w/ AMD Ryzen 3900X): ~12.29ms per frame to ~8.09ms;
Chrome 87 (w/ Snapdragon 435): ~156.34ms per frame to ~94.31ms;

cmd/gogio: restore package path handling

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.

op/clip: handle zero Cube

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.

internal/ops: remove some bounds checks

Currently BCE is unable to understand that the accesses in the code are
safe. Added an explicit slice to make the length bounds obvious.

Signed-off-by: Egon Elbre <egonelbre@gmail.com>
Many operations do not pass refs to Write. Similarly adding
...interface{} requires constructing a slice, which is slow.

This cuts about 100ns from RRect and Border benchmark.

op/clip: expose LineTo and QuadTo

Using delta position with Line and Quad can drift over successive calls.
Also, in some cases it's much more convenient to use absolute
coordinates rather than relative.

app/internal/window: add support for system.CommandBack on wasm

To get the `popstate` we need to create a new entry into
the browser history. Then, Gio will handle the "back" and
"forward" of the page.

In some browsers (Chrome 87/Edge 87): The user must
click inside the window/page at least one time. It will not
work if the user leaves the page  (clicking back button)
without interaction with Gio.

app/internal/window: mitigate keyboard issue on WASM iOS

That change mitigates the issue gio#150 and gio#166. The
iOS can only `focus()` as a response to touchstart/click
events. We can't `focus()` at random, without user interaction.

The `w.requestFocus` will try to focus on the next `touchstart`,
which may need some "double click" in some cases. That mitigates
the issue, but doesn't fixes completely, but open the keyboard. (:

I didn't notice any side-effect of that change on Android and on
Windows.

app/internal/window: remove context-menu (right-click) for wasm

The context-menu seems useless. The only action available, on the
context-menu is to "Save image": which gives a black image.

I think it's better to remove it. The right-click still work and still
provide `pointer.Event`.

cmd,example: fix uses of color.NRGBA

all: use color.NRGBA in public API

color.RGBA has two problems with regards to using it.

First the color values need to be premultiplied, whereas most APIs
have non-premultiplied values. This is mainly to preserve color components
with low alpha values.

Second there are two ways to premultiply with sRGB. One is to premultiply
after sRGB conversion, the other is before. This makes using the API more
confusing.

Using color.NRGBA in sRGB makes it align with CSS.e
