Andrew Borodin 2cd33ad0d5 Convert widget coordinates from global to local and vice versa.
Add two widget callbacks:
  * (make_global): convert widget coordinates from local (relative to
    owner) to global (screen).
  * (make_local): convert widget coordinates from global (screen) to
    local (relative to owner).

Such conversions are required when nested widgets and groups are added to
or removed from another groups.

Overview
--------

This tree contains unit tests.

To compile and run the tests, do 'make check' (either in the top folder,
or just in the folder containing the tests you're interested in).

IMPORTANT: To compile the tests, you need to have the "Check" unit
testing framework[1] installed.[2] If you have it installed, you will see
"Unit tests: yes" in configure's summary message; if you don't see this
message, you won't be able to compile the tests.[3]

Tips and tricks
---------------

* To be able to step with the debugger into test code, see [4]. E.g., do:

    $ export CK_FORK=no

[2]: Your package manager likely has it.
[3]: Actually, some tests (like src/vfs/extfs/helpers-list) don't use
     this framework and will compile just fine. But that's the exception.
