Mice drags scroll on Android by convention. Further, ChromeOS converts
two-finger touchpad scroll gestures to press-drag with Source == Mouse.

for closing those windows.

An interface for scaling dp and sp is overkill, at least for all
current uses. Make it a concrete struct type, and rename it to the
shorter and more precise Metric.

At least one Samsung S9 device ignores the sRGB setting if the context
wasn't created with alpha in its attributes.

This adds a --disable flag to the kitchen example so that it's easy
to preview what all widgets look like when they are disabled.

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.

that it had left just before click would complete.
