re-check the WGL extension. But, maybe locally defined extensions

The code which changes the X11 video mode has an off-by-one error,

* Use slightly more compatible cursor shapes for GLUT_CURSOR_RIGHT_ARROW
and GLUT_CURSOR_LEFT_ARROW.
* Refactored and fixed the erroneous code for GLUT_CURSOR_NONE.
* Removed the incorrect use of XFreeCursor and use a cache of cursors
instead. Cursors are never freed now, we could do this e.g. via
reference countig if this is really needed.
* Fixed error handling.
* Unknown cursor types are an error now.
* Now the window state always corresponds to the wanted cursorID, even in
the case of GLUT_CURSOR_FULL_CROSSHAIR.
NOTE: I am not sure where the cursor cache should really reside, currently it
is simply a file-local variable.

(Offscreen looks and acts like a top-level window in many
ways.)
* During the life of the offscreen "window", various window-management
functions are modified to respect offscreen status.
(Excepting reshaping windows, there is not much useful interpretation
for managment of offscreen areas. Reshaping is possibly more work
than it's worth to support, and GLUT specs allow us to ignore the
request.)
* Cleanup for "offscreen" windows is a little different than for regular
windows.
Windows still don't start up quite ideally. Offscreen windows should
probably get a reshape event, but not a display.

order. This cased a crash when the call to glutDestroyWindow() for a sub
windows was immediately followed by a call to glutDestroyWindow() for it's
parent. fgCloseWindows() would call fgDestroyWindow() for the parent first
fgDestroyWindws() would recurse over the children and then fgCloseWindows()
would call fgDestroyWindow() again for the child.
I've replaced the single linked list with one of our two way link list
structures. I've also moved it into fgStructure because that seemed the
consistent thing to do.

{...Height}. Those are *not* records of the old values, but rather
of the *desired* *new* values, hence it was inappropriate to use them

problems.
So, I created OldHeight and OldWidth in the window State structure,
and *those* do what I require.
I also stripped out the obsolete comment about getting extra/bogus
reshape events. (Though I maintain that an application should be
robust against them, freeglut should no longer generate them if the
window has not changed size since last reported.)

callback handling would result in effectively a glutReshapeWindow()).
The code is now system-dependant. It should be abstracted to a function,
but is presently copied in two places. Sorry.
Also, inverted the order of the associated if()/else check (in both
WIN32 and UNIX_X11 branches) since the former "else" part was a one-line
callback invocation.
This fixes two seemingly unrelated bugs that I was seeing in UNIX_X11.

* We forgot to bump our version number in freeglut_internal.h
It is now at 2.0.2 (actually, I think that 2.1.0 might be
a better choice), which is presumably going to be our next
formal release. 2.0.1 is incorrectly identified as 2.0.0 in
the header.
* A typo in a comment has been corrected ("than"/"that").
* Numerous "manual" checks for callbacks are omitted now, since
INVOKE_WCB() does this for us. These were holdovers from the
pre-INVOKE_WCB() days. There may be some very subtle changes
in freeglut behavior, since freeglut used to test the callbacks
a little earlier in some cases and may have skipped some minor
things (like changes to the current window) in some special cases,
otherwise. It is not believed that any documented behavior is
broken, and it is unlikely---not to say impossible---that any
extant applications will detect the change. It is even possible
that there is no external behavioral change in freeglut.
This also significantly simplifies some sections of code that used
to have conditional execution. "Unconditional code is simpler code"
as one of the comments used to say.
* Lots of XXX commentary is now removed. Some of it was obsoleted
by other changes, some by changes from John.

efficiently be postponed, quite easily---and which GLUT promises *is* to
be postponed. (It is unlikely that the difference will break any apps, but
postponing should be easy...)
No real change, just a comment in the code.

few in the "one" demo, it seems, and some more crept back into
freeglut_(ext|font).c, presumably due to my own edits when I forgot to
use the "freeglut-c-mode" in EMACS.)

glutInit() in general, since it allows the user to override settings via
{argc, argv} command-line params.)

Added entries summarizing my commits since September or late August, for
the benefit of those lacking both CVS and web access.

WIN32 expected us to pass the message on up the chain (or do something
else with it), rather than just throwing away the event, for a certain
class of events. (See the diffs for more details.)
The code is also slightly reformatted from what was previously in the
repository.

Plus updated *.dsp and *.dsw files to reflect the new freeglut header
file.
NOTE: The prior version of the *.dsw file does not in fact have CRs. I
thought that it did. For consistancy, I am not putting them in in this
version, either. (At least one person said that his MSVC++ system is
happy with the current files. If there are problems, we can easily add
the CRs, but that should be a separate commit...)

This demo shows the use of every callback that you can register with
freeglut, and also generates event reports so that you can see what is
happening to the program as it runs.
Not much to look at, but both utilitarian and a practical example.
Please double-check that I updated everything that needs to be updated.
I reran autogen.sh and ./configure, and it built okay for me. (^&

Oh well... Should be no functional changes. Should be pretty
close to in-line with the style of changes that I've been making else-
where.

on, leaving Destroy to be cleared later after the last possible point
where it should be invoked.

in fghDisplayMenuBox(). The local variable was already defined and used
for some purposes, so we might as well use it throughout. It does serve
to shorten and clarify the code a bit---though I have mixed feelings about
creating aliases that way.
Still, the variable already existed and was already used in places. (We
could even move it into the freeglut state, or make it a {const static}
value...)
Oh well. Stuff to ponder.

in the freeglut_cursor.c file's "Open issues" comment are now satisfactor-
ily closed.
I also partially implemented some error-checking, using my limited
understanding of how Xlib users are supposed to do this. (No one commented
about the lack of error-checking, pro or con. Perhaps someone will care to
comment now?)
At present, it just will print out a warning, via fgWarning(). In part
because I'm not sure what is best to do, and in part because failure to
set the cursor type is probably not a fatal problem.

freeglut's style. Mostly re-indenting and splitting long lines.
For those that may be concerned: No, I didn't do any more arrangments
of the form (CONST == a) rather than (a == CONST). (^&

Previously, it picked out two adjacent bits in the result of rand().
Unfortunately, these adjacent bits (at least on NetBSD) have a certain
amount of dependance. After a period (perhaps a thousand or so?), it
starts to repeat the pattern of those two bits. (I think; I haven't
actually tested that directly.) This presumably is locking it into a
an an N-way attractor on the "snowflake", such that if you zoom in a
ways, you will start to see some spots *quickly* are colored, and
others are *never* colored.
What I've done now is to pick up two widely-spaced bits in a single
rand() call. (Perhaps we would do as well to pick up something like
bit #16 from two consecutive rand() calls?) These widely-spaced bits
have a lower statistical dependance on one another (if I can get away
with using that term for an arithmetic operation; though since stats
has more to do with sampling and less to do with true randomness, I
may be safe).
The net effect, at leats on NetBSD, is far better snowflake if you zoom
in on it.

[This] implements the visible/invisible for Windows. It does
NOT call the visibility callback, though.

rather than { ... } for the INVOKE_WCB() macro. This lets it
be used "more like a function", in that:
if( ... )
INVOKE_WCB( ... );
else
...
...is now legal.
