Insets is like image.Rectangle, but with properly named fields
and ui.Value instead of raw ints to make use with the layout
package easier.

To keep the interface slim, remove the helper methods and shorten
the essential method, Pixels, to Px.
Add and use unexported Config implementation in the app package.

The dp and sp units are approximate and mostly used for layout
dimensions that operate in whole pixels. This change alters the
Config methods to return pixels in ints instead of floats, which
results in smoother use for layout and emphasize the inexactness of
the device independent units.
Clients can still access to raw PxPrDp and PxPrSp factors from
Config.

IsAlive races with the StageDead event: if the client checks IsAlive
after the stage is updated to StageDead but before having received
the StageDead it will exit the event loop, blocking the StageDead
to ever arrive.
Remove IsAlive and let the client rely only on the StageDead to exit
its event loop.

A Window.Redraw called after the client has completed building a
frame and before Window.Draw resets the redraw flag is effectively
ignored. Move the flag reset earlier to just before the client is
asked to build the frame, to ensure that no state updates are lost.
Tighten and simplify the locking while we're here.

We are going to encourage a model where pointers to a central
(program global) Configs are passed to widgets at setup time, and
not pass Configs at every frame.
That way, the global Gonfig can change, but the pointers won't need
updating.
This change only switches the Draw event's Config pointer to a value
to avoid tempting programs to use the event Config instead of
updating their own central Configs.

Wayland requires its clients to handle key repeating themselves.
Our strategy is simple: start a timer on key down and fire key
events at regular intervals until another key event arrives.
However, if the program blocks the event loop while processing a
synchronous event, key repeats might pile up before the stopping
key event is processed.
This change use the timestamp of the stopping key event to only
dispatch the repeats queued up before the stop time.

We don't have full IME-aware editor yet. Fortunately, the BaseInputConnection
has a "dummy mode" setting to allow us to receive input from the fancier keyboards
without implementing the full IME interface.
Fixes gio#7 (I hope; I tested with SwiftKey that had the same symptoms)

It seems that the iOS simulator can return NaN from texture2D, so
even though width == 0, the resulting cover is not.

With a <textarea> DOM element pressing the enter key will result in
a "Enter" key down event and a "\n" input event. We're only
interested in the key event, so switching to a single line <input>
avoids the extra "\n".

To avoid passing a queue type for each kind of input (pointer, key),
introduce package input for mapping a handler key to all input events.
Future input sources can be added without changes to programs, and
as an added bonus, event ordering is preserved across input sources.

Instead of allocating and constructing a clip path, store path data
directly in op lists. Use separate op lists for cached text layout
