The fix for #605 moved the disabling of event delivery from Source
to Context to enable disabled Contexts to still react to commands
(invalidate, focus etc.). However, that change in turn caused #641 where
the exported Context.Source field would no longer know not to deliver
events.
This change partially reverts the fix for #605 by moving disabledness
back to Source, fixing #641. Disabled Sources are left capable of
executing commands, thus keeping #605 fixed.
Thanks to Chris et al for keeping the use-cases straight enough for me
to come up with this (hopefully final) fix.

An IME session must be discarded when its text content no longer matches
the underlying text component content. However, the check for matching
was too pessimistic; the IME session would be discarded if the new
snippet from the text component was not equal to the snippet reported to
the IME. This change implements a refined check that only discards a
session if the content of the overlap between the new and old snippets
don't match.
Fixes an IME issue reported by Zhang Zj.

The fix for #616 went to far by attempting to support macOS key bindings
through doCommandBySelector. Issue #625 is a consequence, but more
fundamentally, key bindings does not work with support for key.Release
events.
Remove key binding translation and fix#626, and add a check whether an
IME swallowed a key event, keeping #616 fixed.
While here, replace the KEY_ constants with ASCII codes.

In order to avoid DLL preloading attacks, we should be careful about where we
load DLLs from. These packages load graphics DLLs, which may be provided by the
OS, by a graphics vendor, or even by individual applications. As such, we can't
restrict loading them to just system32-provided paths. Instead, we invoke
LoadLibraryEx [0] with the LOAD_LIBRARY_SEARCH_DEFAULT_DIRS path, which will search
system32, application-defined paths, and the path of the primary application
executable. This mode ignores the system %PATH% variable, which dramatically
reduces the attack surface of malicious or unintended DLLs.
Applications may add custom paths to the search list by calling the standard
windows AddDllDirectory function [1] prior to attempting to initialize GL.

The typesetting package has smarter line wrapping now, which is making our
test text require fewer lines to display. We needed to update the expected
data accordingly.
I've also added a feature that takes a screenshot of the rendered output of
one of our most complex cursoring tests. This will make it much easier to
verify its behavior in the future. This feature currently only triggers if
the test case fails.

Widgets such as Editor use certain key events such as the backspace key
to implement text editing. On macOS, such key events are sometimes used
by an input method, and in those cases the key effect would be applied
twice: first by the IME and then the Editor.
Report such key events through the doCommandBySelector callback, which
receives key events not handled by the IME.

When a GPU error occurs forcing the reporting of a DestroyEvent is not
appropriate, because the backend that controls the underlying window
is not aware of the error and will continue to report events.
Replace the crude DestroyEvent by stashing the error and asking the
window nicely to close. The, report the stashed error in the
otherwise regular DestroyEvent.
Hopefully, this second attempt fixes#603.

Before this change, the window state was explicitly updated whenever
Window.Option was called. However, the system may also change window
state as a result of user gestures, but those changes did not result in
ConfigEvents reflecting them.
Remove the explicit state updates and track them when the system tells
us it has changed.
This is a step towards fixing #600 which require accurate window state
tracking.
