This commit configures all remaining widgets to draw themselves in a disabled state
when their layout.Context is disabled. A description of the
strategy employed by each follows:
- Checkbox and RadioButton: Draws the icon component in a lighter color. Currently the label text is left
in its default color.
- ProgressBar: The "progress" color is lightened, but not as much as the background color. This makes the current progress value still readable.
- Editor: The cursor is no longer drawn and the text is lightened.
- Switch: The track is unchanged, but the circular "thumb" component is lightened.

Do is a function for accessing the underlying Android View in a safe
context, the main thread. Do is
- more general than RegisterFragment and may be expanded to other platforms
- simpler to implement (from the Gio side)
and as a bonus, the Do implementation avoids a race condition where
a call to RegisterFragment during an Activity re-create would be ignored.

The Activity context may not be available, so it's safer and simpler
to use the always available app context.

Fixes misaligned carets when the Editor text contains code points
represented by multiple UTF-8 bytes. Line lengths should be
measured in bytes instead of glyphs for caret positioning.

It's more intuitive to specify the weight as a ratio of the total
weight of all Flexed children than to specify the ratio of the
flexable space.

Then, make layout.Context.Now a field, copied from FrameEvent.Now.
API change:
gofmt -r 'gtx.Now() -> gtx.Now'

The layout package imports io/system anyway, so depending on
FrameEvent does not introduce new dependencies.
API change. Use gofmt to adjust your code:
gofmt -r 'layout.NewContext(a, b, c, d) -> layout.NewContext(a, e)'

When a clickable is pressed and dragged any enclosing List will grab and
cancels the press. To minimize visual dicontinuity, smoothly fade in the
inkwell.

Fixes a problem where a touch Release would signal gesture.Click
that it had left just before click would complete.

Use greater-than-or-equal test and saturate the z depth buffer
when more than 65k objects are drawn.

This adds a simple button that defaults to being disabled, but can
be enabled by toggling the state of the existing Switch widget.

This leverages the new semantics of a disabled layout.Context
to draw all of the button types in a disabled state.

This adds a simple method that returns a copy of the Context
with no event queue. Widgets laid out with this Context will
never receive events, and can check whether the event queue
is nil as a hint for whether or not to draw themselves as
disabled.

There may be unrelated events in the queue, so it's not appropriate
to clear the queue just because an input Cancel event occurs.
