(since yesterday's one had very confusing note, and
 now I found a fix for the window resizing problem)

Last update to this file.

Now I know that Steven's working on this,
I won't spend my time in updating this,
but I don't like to leave it with some serious defects...
And since I like his tile resiziing code, I replaced
original simplistic code with his.

Most importantly, window resizing still has some problems
with this.  "size_allocate" should be the place to do that,
but, strangely, minimum size given by the geometry hints
isn't respected by the window manager, nor the size constraint
code in the size allocation handler doesn't work...

If anyone likes Windows/Mac-like interface of this
file, please feel free to take it or modify as you like,
for example:

1) As SF explained in the r.g.r.a discussion, restoration of
backing store pixmaps helps client-server setups a lot. This
can be another runtime option. You might go extreme to store
_tiles_ in a pixmap under such configuration.

2) Those pixmap also allow us to implement double buffering.
I suspect current [Z] version works faster than the original
by buffering character-by-character drawing in Term_text_gtk
and Term_pict_gtk. I replaced the former with a single call
to gdk_draw_text() and there was a noticeable performance gain...
Use a GdkRectangle to keep track of bounding rect of dirty area
and copy that to a corresponding drawing area when appropriate
- maybe in TERM_XTRA_FRESH, TERM_XTRA_EVENT and TERM_XTRA_DELAY,
but I don't know for sure.

3) The tile rescaling module should have reference count
and windows using the same font_wid & font_hgt should
share the same scaled image.

For Angband 2.9.3

main-gtk.c by Robert Ruehlmann (rr9@angband.org)

Graphics code based on works by various contributors to X11, XAW,
Windows and Mac ports

GdkRGB wrapper and conversion of colour & tiles support by
pelpel (kazuo@sta.att.ne.jp), who also rewrote menu routines and
added a couple of callbacks to support resizing.

All of my modifications are released under the Angband/GPL dual licence.
Since I read RR's main-gtk.c and Gimp + Gtk+ source code, it couldn't
be otherwise, and I like that.

(On this file)
Gtk/Gdk has two different layers of image drawing, the first and low level
one - GdkImage and GdkColor are wrappers of XImage and XColor, and the
other, GdkRGB, isolates programmes from them and tries to produce best
possible results with available colour depth, while resorts to dithering
on 8bpp X servers -- Yes, it works with 8bpp, even with Adam Bolt tiles and
smooth rescaling. I tested that because this was the only type of
X servers I could run on my old ix86 machines until quite recently.
I believe many run Linux on older PCs, which is more than enough
for Open Source Un*ces, so I hope this helps them to play Angband on
our favourite OS.

P.S. This file has nothing to do with another upload based on main-gtk.c
