The OpenGL backend needs it, but I keep forgetting to test it when
rearranging the window rendering code. The gogio X11 end-to-end test
tests this issue, but unfortunately it is disabled because of flakiness.

A recent change broke custom rendering by not allowing the client
to continue after calling FrameEvent.Frame. This change makes sure
the client is allowed to continue regardless of rendering mode.

Android doesn't distinguish between the arrow keys on a keyboard and the
directional keys on a remote control, so there's no way to move the caret
in an Editor with arrow keys. This change updates the Android port to map
Android's DPAD_* key codes to the arrow key names, fixing caret movement.
The change also updates Editor to only request arrow keys that actually move
the caret, to keep directional focus movement working.

Prior to this change an editor with no content and a zero minimum
constraint would return itself has having width zero. This
prevented users from being able to see the editor when they
moved focus to it, as it could not display its caret. This
simple change ensures that, at minimum, the editor returns
its dimensions to include the width of a caret.

Updated the documentation for layout.List to include the details about how
drawing is performed for items in it. This gives the user an understanding about
how so many items can be drawn for performance.

If the currently focused handler don't want the key event, try every
other handler, from top to bottom. This change requires widgets to
only react when focused.

Instead of cmpletely replacing the IME snippet for every update, expand
the old range if there is overlap. This change avoids never-ending
restarts of the IME on Android where snippets are expanded in two
calls, one for expanding before the selection and one for exanding after
the selection.

It's much simpler to map the Android back button to a key.Event and
let the usual key filtering determine whether to block its default
behaviour.

This change adds key.NameUp/Down/Left/Right and maps the Android TV
remote directional keys to them. As a side-effect a key.InputOp can
now receive directional keys (and block their focus movement).

Before this change, Tab and Shift-Tab would always result in focus
movement. This this change, a key.InputOp with a matching Keys set
will block focus movement and deliver the events to it.

Before this change, every Event would be passed to the focused InputOp
tag, making it impossible to implement, say, program-wide shortcuts.
This change implements key.Event routing similar to how pointer.Events
are routed: every InputOp describes the set of keys it can handle, and
the router use that information to deliver an Event to the matching
handler.
This is an API change, because every InputOp must now include a filter
matching the keys it wants to handle.

Before this change, synthetic events such as scrolling caused by
focus movement would use semantic information to determine potential
receivers. However, there can only be one handler per area so sibling
handlers would not be considered. This change makes the event delivery
traverse the entire tree of handlers, including siblings.

We're about the express sets of key combinations as <modifiers>-<keys>
where modifiers are separated by dashes as well. To make Modifers.String
useful for expressing key sets, change its separator to "-".

We already have precedence for word-named keys ("Space") and the new
names are less obscure and matches Modifiers.String.

OpenGL ES 2.0 doesn't support GL_PACK_ROW_LENGTH, so this change implements

We should return as soon as possible from FrameEvent.Frame to allow the main
goroutine to continue processing other tasks. Whereas GPU.Frame may touch
the frame ops, GPU.Present will not, so this change moves Present to after
returning from FrameEvent.Frame.
This is a variant of 38ff78df5d that
works on OpenGL where context locking is required.

Clipping all children once to the entire List area is enough. The
change was motivated by #389 where individual child clips would
make it harder for focus scroll heuristics to work.

List was recently changed to include an extra child at each end, to
automatically scroll when reaching the end of a focus direction. However,
if List includes unfocusable children that strategy may fail. This change
adds another fallback where app.Window will scroll a constant amount in
the focus direction, to reveal more children.

Enter/Leave events make sense for mouse pointers, to track hover
status. It doesn't make sense to track hover for touch input, so
this change stops pointer.Enter and pointer.Leave from being
emitted for pointer.Touch sources.
