65dde7f632 Cleanup pass after committing callback conversion (from structure to
array-of-pointers).  Mostly deleted commented-out struct-based code.
Also added some XXX comments that I though should be pondered.  (My
own pair of eyes, and one brain cell, were not sufficient at this time
to decide what to do for those ponderables.  (^&)

80a523394c Converted the "Callbacks" structure (with named members holding individual
callback pointers) to a "CallBacks" array in fgState.  (This is to allow
us to write a loop to clear all callbacks from windows when the window is
dead/dying.  Using this, we can safely assign NULL to each in a loop.)

Support includes two new macros, FETCH_WCB() and INVOKE_WCB().  See
freeglut_internal.h for more details there.

Some typedefs of function pointer types were altered to make them more
uniform (necessary for the macros).

All references to window-based callbacks in freeglut are updated to
use the new macros.

Old usages will cause compile-time errors.

As a side bonus, the new invocation macro sets the current window and
checks pointers so that these common steps can be uniformly done on
every window-based callback.  This makes it easier to do things right.
At the same time, the array notation (and now required associated casts)
make it harder to bypass the macros and abuse the function pointers,
in general.

After this commit, I will go through the code and clean up dangling issues
about formatting.  This commit is just a "it now works, let's checkpoint it"
type of affair.

d5d4789b6b Per John's emailed desire to have all files obey UNIX EOL conventions,
I have stripped out carriage returns from this file.

to get local copies of each and first match their EOL convnetions.

31c0809e28 * Fixed a bug in the X11 handling of scrollwheel/mouse. The old code,
I believe, checked if *either* a wheel or button callback was set,
   and then decided which to use---and unconditionally called it.
   I left the "either" check in, but added additional checks before
   actually doing the invocation.
 * Lots of reformatting.  Massive.  The usual suspects, though, and fairly
   trivial: Re-indenting to standard size, shuffling some spaces to match
   the freeglut "standard" of:
     if( ... )
   ...and:
     func( ... )

d1bfaa5c4b Noted by XXX comments that the XFlush() calls probably shouldn't be there.
Flushing the X protocol stack every little bit both adds clutter to the
code and may impede performance.

It seems that we should be able to get rid of these, though
allowing client code to directly call glutMainLoopEvent() does make it
a little more complicated.

Something to ponder.

   (The error-check was on window creation; we don't want to

    Also, assert()s really tell us more about programming errors,
    rather than run-time errors, so it is a little misleading to
    use assert() for error-checks, even if you can depend upon
    assert()s never being compiled away to null statements.)

807042d126 There should be no changes to code functionality, though a fair bit of
little changes to the code appearance.

 * Fit the comments at the start of the file to fit 80 columns.
 * Noted an unusual feature of the ATTRIB() macro.
 * Added ATTRIB_VAL() macro which is really just two ATTRIB()s.
   This lets us put things like {ATTRIB (GLX_RED_SIZE); ATTRIB (1);}
   on one statement: {ATTRIB_VAL (GLX_RED_SIZE, 1);}.
   I did this to preserve some of the layout of information while also
   avoiding the nasty semi-visible ";" in the middle of a line of code.
   And by putting the {braces} in the macro definition, I was able to
   visually clean code of the form:
       if (condition)
       {
           ATTRIB( X ); ATTRIB( 1 );
       }
   ...rewriting as:
       if (condition)
           ATTRIB_VAL( X, 1 );
 * Eliminated a bunch of say-nothing-new comments in fgChooseVisual().
 * Combined some semi-useful comments into a block comment summarizing
   a loop.

92b5fb9d59 Finished off most of the issues with freeglut_structure.c, from a stylistic
point of view (at least, insofar as: The original file's code was INCON-
SISTANT.  I did not remove the "!= NULL" stuff, did not address the
shortest-branch-first issue for if-else statements, and left some rather
ugly "if (x) {... return y} /* else do this */ return NULL;" garbage.
This should, I think, be re-written as "if (x) return y; else return NULL;"
or even better, "ret = NULL; if (x) ret = y; return ret;"

In short, the code still has some issues, but I think that it's a bit
better.

(Oh, I also got rid of oustanding TABs.)

c2f23f0bb2 Grrr. My attempt to commit got aborted, and the commit message was lost.
Now I've lost track of what I said I'd done.  Something like:

 * Fixed some issues with multiple wheels.
 * Noted in comments some issues about other-than-3-real-buttons.
 * Fixed formatting to fit 80 columns.
 * Removed some BCPL/C++ style comments (//) that are not legal, and
   which, if memory servers, are not even strictly legal when disabled
   by preprocessor directives.  E.g.,

   #if 0
     not-syntactically-valid-C
   #endif

   ...is not legal.  Though most cpp's will discard the bracketed material
   completely before the main C compiler pass has a chance to analyze the
   syntax.  (MSVC++ and GCC both don't seem to mind the BCPL style comments
   in plain C, but let's keep the sources clean, eh?)
 * Fixed a problem that would have caused freeglut to report doubled
   wheel events under XFree86.

Not tested other than compiling.  Personally, I think that the interface
is inherently broken at this point unless you are willing to get user-
configuration.  (Which would then solve the complaint that Steve had
about computing the tick-size on behalf of applications.)  I.e., there
is NO WAY to know if we have the right buttons to start wheels at, or
if there are any buttons after the first wheel(s), etc.  We just have to
guess---and if we are wrong, we can get varying degrees of brokeness.

b46806dc31 Previous changes were made without the freeglut major mode in EMACS.
Re-tweaked some lines (mostly got rid of some TABs, but also resulted
in some changed indentation).

Reformatted a big comment to fit to 80 columns.

Removed bogus references to "Linux".  (UNIX, and/or X11 were relavent,
and "UNIX/X11" was substituted for "Linux" in those places.  This includes
UNIX-alike systems.)

2abe3abee5 Rewrote the TODO BEFORE THE STABLE RELEASE comment to fit to 80 columns.
Cleanup of fghGetConfig().  (One return statement, simpler code.)

Made glutSetOption() have a more consistant style---and also got its lines
to stay under 80 columns.

3365de2c4a Got the last of the say-nothing-new comments in freeglut_misc.c.
(I would have picked them up before, but wanted the bug-fix and
conversion-to-error-message changes to go in before I did more
superficial stuff.)

9da07cd41f * Fixed a bug that I introduced in fgWarning()/fgError(): I thought that
((a) || (b)) was defined to have value as:
     (a) if (a) != 0
     (b) if (a) == 0

   ...instead, it has value 0/1.  This was causing a bug.  It's probably
   just as well, since what I was trying to do definitely fell into the
   category of "clever code" rather than "clear code".

   Sorry.

 * Made glutSetKeyRepeat() call fgError() if you go out of range.  (The
   old code silently did nothing---not even a warning.)

   If it is really desirable to keep running, we should probably at least
   generate an fgWarning().

 * Deleted some say-nothing-new comments.

 * XXX added: Is glutSetKeyRepeat() deprecated?

4672072aa7 Commit, mostly of work from John:
* Removed some say-nothing-useful comments.
 * Added some tentative mouse-wheel support.
 * Fairly massive reformatting of code.

I made some secondary changes to his changes:

 * One compilation error was fixed (missing close-paren + semicolon).
 * Deleted a few ore say-nothing-useful comments.
 * Some of John's code was strangely formatted to the point that it
   seemed completely out of place, so I took the liberty of reformatting
   it.  Since I used GNU EMACS's <tab> key (which re-indents rather than
   inserts TAB characters), I had to propogate some indentation changes
   a little further than the bare necessity to match up with John's
   changes.  (John seems to shoot for 2-space indents, while EMACS
   (and I, I confess) strongly prefer 4-space indents.  The code that
   I was re-indenting had been put to 8-space indents, however.)

I have *not* tested the code beyond compiling.  I assume that John did
(and that the compilation error was a result a minor change just before
asking me to commit).
