84b4821d43 widgets: add TextView widget 
The TextView widget provides a simple way to show text content in
a scrollable window.

This implementation does not offer automatic line wrapping for now.

Text content is backed by the Buffer struct. The buffer can be styled
for visually appealing and colorful content, for example to provide
a syntax highlighting.

The buffer provides a writer() interface which allows providing content
from a stream, such as logging.

f25b8ab421 widgets: add ScrollView widget 
The ScrollView widget can be used to introduce scrollable elements into
existing widgets.

To use the ScrollView, you must use the ScrollView's writeCell and
readCell functions rather than the ones from Window.

fbaa6ca8df fix: manually reschedule to avoid hang on macOS 
libxev's .rearm semantics are unfortunately not very
portable---rescheduling the exact same event on macOS / kqueue seems
to cause the event loop to hang, while manually rescheduling and
returning .disarm does not.

bbd9184e00 loop: add an xev loop implementation 
This loop adds an xev.File wrapper called TtyWatcher which delivers
events to the users callback. Note that this implementation does not
handle any of the writes. Writes are always safe in the main thread, so
we let users decide how they will schedule those (buffered writers, xev
writes, etc)

1c11333717 tty: do not close /dev/tty on macos 
Attempting to close /dev/tty may block indefinitely on macos if another
thread is already blocked on a read operation. As there is no practical
use for closing /dev/tty on exit besides unblocking other threads (which
does not work on macos anyway) we can just skip the close call.

55809160b9 vaxis: detect pixel mouse mode and translate coordinates to cell offsets 
This detects support for pixel mouse mode so it can be enabled only
if supported.

This also translates pixel coordinates to something more compatible
with plaine cell coordinates. This make it much easier to write
applications that support both.
