Improvements to the Win32 screen driver

 . Rationalized names and the interface to some primitives.

 . Added screen name feature (like X version)

 . Ensured that windows are closed before exit / disk-restore.

 . Fixed bug in screen resize (you *have* to guard against resizing to
   the same size otherwise the rest of the system allocates new
   matrixes and then decides to optimize the screen reorganization,
   leading to random stuff being copied from the uninitialized
   matrixes to the screen).

 . The Close Window menu item now closes the window if there are more
   than one, otherwise it behaves like ^X ^C

 . Debugged multiple screens.  Added a whole load of black magick for
   keeping Edwin's idea of the selected-screen in synch with the
   Windows screen with the input focus.

 . There is no need to hide the cursor (Caret) during redisplay as
   windows does this anyway, and manually hiding it causes visible
   caret flicker.

30 years agoChanging WITHOUT-INTERRUPTS to WITH-EDITOR-INTERRUPTS-DISABLED

Changing WITHOUT-INTERRUPTS to WITH-EDITOR-INTERRUPTS-DISABLED

WITH-EDITOR-INTERRUPTS-DISABLED is required in the running editor but
the first buffer is created before the editor structure exists, and

dumping the band) -- e.g vc.scm.

WITHOUT-EDITOR-INTERRUPTS choses to do either a WITHOUT-INTERRUPTS or
a WITH-EDITOR-INTERRUPTS-DISABLED (confused?).  Perhaps
WITH-EDITOR-INTERRUPTS-DISABLED ought to have this behaviour.

Numerous changes, either bug fixes or changes to accomodate the new
Edwin Win32 Screen.

The events have been tweaked.

Several entry points have been exported or written to allow
efficient update of the display character grid by the new Edwin
Win32 Screen driver.

The display code has been fixed.  It was seriously broken and then
heavily kludged-upon.  Now it does the right thing for WM_PAINT and
WM_ERASEBKGND.  This fixes the windows 3.1 problem of repainting the
whole screen of a resize.  It would probably be even better to
eliminate WM_ERASEBKGND completely and make the resize code invalidate
the orphan pixels which do not correspond to a character position.
This would prevent the `flash' as the screen is repainted after a
resize and then repainted again after Edwin has decided (or not) to
change the display (line wraps etc) to fit the new size.

Keyboard.  Added direct code for all the `function' keys (like PgUp,
f5 etc).  Removed MIT_TranslateMessage, which was the wrong thing
because it screwed non-edwin windows (like buttons, dialogs, menus,
...).  Most of the keys are now handled specially at the WM_KEYDOWN
level, avoiding WM_CHAR.  This makes it possible to generate something
for C-7 and M-C-<key>.  This is done in a very US keybaord layout
specific way.  The right thing is to ask what the key normally does
(the KEYMAP program on the Developer's network does this) and then do
the emacs thing only if the key is not o-umlaut or
grave-accent-modifier (`deadkey') or whatever.

Changes to merge with Win32 edwin screen driver and support.

The main change is the addition of a new Edwin screen device for
Win32.  The new device implements special keys and mouse buttons.  A
certain degree of reorganization has been done to make the X and Win32
versions as similar as possible.  Some things that used to be called
X-MUMBLE are now just called MUMBLE (e.g BUTTON1-UP, MOUSE-SET-POINT).

  key-w32.scm, key-x11.scm:  System specific handling of special keys

    cannot generate them.  (I have a prototype fix for the console

Changed C_call_scheme to preserve and restore `last_return_code'.
This fixes a bug which manifests as an access violation during GC.

The GC bug happened because the incorrect value of `last_return_code'
left after the recursive interpretation caused a negative stack
segment size to be computed.  When this was boxed as an unsigned value
it became an illegal pointer object.  Note that this manifestation
would not have happened with the new tagging scheme.
