cmd/devdraw: avoid use of X button state field
This bug is an intermittent annoyance and does not seem likely to be
fixed soon. It means that every so often my acme becomes unusable
because it behaves as if a mouse button is permanently set.

Avoid that issue by keeping track of mouse button state directly.

While we're about it, fix another annoying issue: under Linux the
FocusOut event reset the kstate field but not the kbuttons field,
meaning that the buttons state could inappropriately persist. This
happened occasionally by accident, but was easy to reproduce: with the
mouse button held down, drag outside the window and click Alt-Tab to
switch away from the window. We see a KeyDown event followed by FocusOut
but no KeyUp event.

This is a port of many Plan 9 libraries and programs to Unix.

Installation

To install, run ./INSTALL. It builds mk and then uses mk to run the rest of the installation.

For more details, see install(1), at install.txt in this directory and at https://9fans.github.io/plan9port/man/man1/install.html.

Documentation

See https://9fans.github.io/plan9port/man/ for more documentation. (Documentation is also in this tree, but you need to run a successful install first. After that, "9 man 1 intro".)

Intro(1) contains a list of man pages that describe new features or differences from Plan 9.

Helping out

If you'd like to help out, great!
