his freeglut_internal.h file where they were wrapping in EMACS; otherwise,
the files are exactly as he sent them to me).
The change unifies the WIN32 and UNIX_X11 code by defining our own
window-handle-type in freeglut_internal.h. This let John rip out some
#if garbage in several places. The result is clearer code.
Thanks, John!

(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.

Moved geometry parsing to after fgInitialize() so we can use the screen size
to correctly calculate negative positions in the geometry string.
Copied the code for XParseGeometry from the X11 sources for use in the
Win32 version.
freeglut now passes test1 of the glut test suite.

fgElapsedTime() now set the start time if Time.Set is false.

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

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

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. (^&

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.

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

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.

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. (^&

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.

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.

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. (^&)

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.

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( ... )

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.

* Removed TABs.
* Made indentation consistant.
* Deleted say-nothing-new comments.
* Changed an *error*check* from an assert to an if().
(The error-check was on window creation; we don't want to
lose that if the user compiles with asserts deactivated.
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.)
* Added some XXX comments for things that bear some rumination.

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.

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.

Raised some issues about completeness/correctness of trying to

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.
