354569a7c4 Numerous style normalizations from John:
* Convert "return( value );" to "return value;"
 * Normalize spacing around semicolons.
 * Remove extraneous parens.
 * Split multi-statement lines into multiple lines.  (Mostly things
   of the form: "if( condition ) return;".)

7e7ff3191d All changes are from John, except for:
(a) I re-inserted the meat of a comment that I still feel is relavent.
 (b) I fixed a compile-time error in the UNIX_X11 code where a variable
     is declared after executable code in a block without creating
     a new sub-block for the declaration.

Changes from John include:
 (a) Style revision.
 (b) Changes to postpone the handling of window resizes.

Lots of lines were changed, but I think that thos two cover the ground that
he hit.  See the diffs for details.

d906368add Use XParseGeometry for better geometry parsing.

Sorry, but that's all that I'm up to at the moment.  On the plus,
excepting the font_data file (which I've been skipping), up through
this file, I think that the code style is pretty close to uniform.

1d2ade2f1c Noted one of a few cases where we do something immediately that could more
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.

use the "freeglut-c-mode" in EMACS.)

7621f53262 John's fix for the minimize/close/maximize controls no longer working.
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.

b1c4e6beb8 A *.dsp file for CallbackMaker in the demos.
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...)

6829d65fb3 New demo from John: CallbackMaker.
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.  (^&

6230b2de2a Modified the menus to refer to {border} rather than {FREEGLUT_MENU_BORDER},
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.

fb26d91989 Well, a couple of days have gone by, so I assume that items (a) and (b)
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.

9c070e4f9b Altered the way that the {random} value (from 0..3) is chosen.
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.

like this.  That makes it easier to find the one that you're looking for,

658305f2c9 Added GLUT_CURSOR_NONE support in UNIX_X11 (well, NetBSD; you lot need
to try it on others; (^&).

Deallocated some resources that we are creating.  VERY slight memory leak,
but plugged now.


These two complete the first two "Open issues" ( (a) and (b) ).  The first
one also completes X support for glutSetCursor().  If others can verify,
we can fully demote the outstanding bug over this to WIN32-specific.

I'll delete the dead Open issues and re-letter the others if someone will
cross-check me.  Or if no one says anything in a day or two.  (^&

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.

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.

allowing client code to directly call glutMainLoopEvent() does make it

 * Fit the comments at the start of the file to fit 80 columns.

   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 );

This should, I think, be re-written as "if (x) return y; else return NULL;"

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.

2682a53352 There is a problem with the way I did glutFullscreen() in my last commit.
So I've copied the way the game mode does it.  It's not ideal but it works.
The glutGet() for the window border sizes will also have to be fixed at
some point.

1ac66fba61 Rewrote glutFullscreen().
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.
