aeeabeff93 Slight style improvements. Two rules of thumb that are almost always
good to apply:

 * Don't write a == CONST.  Instead, write CONST == a.  Or, more generally
   (in C like languages): Avoid putting an lvalue on the left-hand side of
   an == comparison.  (For consistancy, I try to avoid lvalues on the left-
   hand side of any comparison---but == is the most notorious.)

   (An "lvalue" is a value that can safely go on the left side of an
   "=" assignment, of course.  (^&)

 * Do not write
       if( !condition )
           return;
       other_thing;
       return;

   (See page 18 of K&P's _The Elements of Programming Style_.)

   Instead, it is better to just write:

       if( condition )
           other_thing;
       return;

   There are times when sacrificing structured programming (e.g., via
   multiple return statements) is okay.  But, here, there is no apparent
   gain---indeed, there seems only loss---in the non-structured code.

869780207d Minor corrections to the UNIX_X11 mouse-wheel support. In part this
reflects that {button} is already shifted to the GLUT numbering, and
hence should be counted as 3&4, 5&6, etc.

The other change was simply to clarify the computation of {direction}.
The original code did some clever arithmetic.  The new code is more
straightforward, even if it requires more lines to express.

array-of-pointers).  Mostly deleted commented-out struct-based code.

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.

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.

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.

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.

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.

It now correctly places the window in X11.
It now uses system dependant code for more efficient use of
windowing system calls.

3d344ad2de Should be no real changes to the code function.
I missed a few lines that went past 80 columns.  (^&

Also made formatting more consistant.

Added a couple of XXX comments re. FreeBSD vs. general BSD #ifdef's.

1b7f3df686 Should be entirely superficial changes to code style:
* Fit lines to 80 columns.  (It does get tiresome seeing long lines
   forced to break by the right-hand border of windows...(^&)
 * Eliminated say-nothing-new comments.
 * Made formatting more consistant in spots.
 * Eliminated some hard TAB characters.

126e447121 Added Thierry's change to include sys/param.h. This lets us pick out version
numbers for OS releases corresponding to system headers.

I modified it to also work with NetBSD; I cannot confirm if it is safe with
any other systems, so it remains protected by a #if.

faf725fe15 Deleted some say-nothing-new comments.
Added some XXX's where comments seemed to require future attention.

Added some new comments with XXX's where future attention seems profitable.

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.)
