Subject: [Handhelds] Microwindows 0.89pre7 released

The long-awaited 0.89pre7 is _finally_ released, and is available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.89pre7.tar.gz

There are some major enhancements in this release, as well as
many small additions and bug fixes required to run well on PDAs,
WebPADs, and set-top boxes.  Some of the major enhancements 
include:

o Complete scancode-mode keyboard driver rewrite.  The Microwindows
keyboard interface is now complete, and all applications now have
access to separate keydown and keyup events for every key on
the keyboard, including function keys, shift/ctrl/alt, as well as additional
keys found on things like the iPAQ.  In addition, all keystrokes are
reported with a unicode value (read from the Linux kernel tables) as
well as an up/down scancode.  This modification changed some of the
earlier contributed keystroke API and it's now far simpler to catch
any keystroke without additional decoding.  This modification was
required for the Doom port to Microwindows, available from the ftp
site.  See mwtypes.h for the new keynames.  The scancode driver
is enabled by setting KBDSCAN=Y in the config file.  The X driver
has been updated as well so that keystrokes are identical when running
Microwindows on X or framebuffer.

o Microwindows now exits with the PAUSE/BREAK key, rather
than the ESC key.  This change makes it harder to accidentally exit.

o Support was added for the G.Mate YOPY PDA.

o Image support is enhanced with PNG, PBM,PGM and PPM
image decoders (thanks Alex)

o Top-level window movement is many times faster using screen-to-screen
blitting when dragging windows around.  (An option in the window manager
also allows drawing an XOR frame instead for slower systems:
OUTLINE_MOVE).

o A very nifty launcher application with an extremely cool set of
screensavers has been added.  Background pixmap support for
tiling, centering and such makes background wallpaper a snap.
A tetris game has been added.  (thanks again to Alex for a heck 
of a lot of work and a great job on all this!)

o Support for 5/5/5 15bpp screens was added.  I finally realized
why my home system 16bpp never looked good!  This change
was required for ongoing work with digital video on Microwindows.

o A pass at a macro-driven Xlib to Nano-X conversion header file,
XtoNX.h, which greatly helps hacking Xlib programs into running easily.

o A number of new API entry points were added, including 
selection api Gr[GetSet]SelectionOwner, GrRequestClientData,
GrSendClientData.  Screen saver support with a new internal
timer mechanism with GrSetScreenSaverTimeout.  GrSetBackgroundPixmap,
GrNewPixmapFromData for X bitmap display conversion.
GrSetWindowTitle, GrSetWindowBorderColor, GrSetWindowBorderSize,
GrSetWindowBackgroundColor for the xfreecell port.

o Extensive automatically generated html/pdf/sgml documentation, which
has been placed in the microwin/doc/nano-X directory.

o FreeType font caching has been added, enabling _much_ faster display
of truetype fonts. (there's still some issues with this, and a change in the
font api will be required for the full fix.)

Some of the big bug fixes that are included are:

o Fix XFree86 4.0 expose event handling when running on newer X11.
o Fixed nasty slow blitting in the X11 screen driver.  (more on this to come)
o Added -mstructure-size-boundary=8 for StrongARM compiles
o Fixed dropped events when running client/server.  This was a big
problem and numerous events were dropped by clients due to a
client/server protocol issue that wasn't handled properly by the client
library.  We've now had to move to a client-side event queue.
o Linker error when building shared libraries fixed

Thanks again to everybody for the extremely numerous contributions and
fixes to this release.  I plan on adding a major improvement to the image/blit
architecture in the next release.
