In `scanprsf.web':

Added the following comment re |Scan_Parse::macro_call_func|:

   A `picture' can't be passed to a macro as a typed parameter,
   because |:=| is used to assign to the variable used within the macro.
   In addition, if a `point' (and presumably any other data type without a default value)
   is passed as a typed parameter, an assignment to this object must already have been
   performed.  Otherwise, the assignment to the variable within the macro will fail.
   !! TODO:  Fix these problems!

Working on |Triangle::is_equal|.  This doesn't work yet.  First, I must write
|Triangle::operator*=| for multiplying a |Triangle| with a |Transform|.
Currently, |Path::operator*=| is used.  The latter function doesn't update
the values of |a|, |b|, |c|, |alpha|, |beta| or |gamma| for the |Triangle|.

Working on |class Matrix|, its functions, and the parser rules for
the corresponding 3DLDF type `matrix'.

Unlike the transformation matrices contained in `transforms',
the number of rows and columns of `matrices' can be set by the user.

|class Matrix| uses data types and functions defined in the GNU Scientific Library
(GSL).  The code from that library is conditionally compiled, depending
on whether it's available on the system on which GNU 3DLDF is installed.

If the GSL is unavailable, the `matrix' type is non-functional
and the functions of `class Matrix' will return "unsuccessfully",
but no parser errors should occur.

Found and fixed a major bug in |Id_Map_Entry_Type::~Id_Map_Entry_Type|
in `imetfncs.web'.  It took me 7 hours to find and fix it.

It was causing this message to be issued:

*** glibc detected *** double free or corruption (fasttop): 0x0869c4f8 ***

I hope it was the only one.

I discovered it because declaring a vector-type variable within a macro definition
wasn't working.  Nor it work to declare one inside a group, e.g.,

begingroup;
bool_point_vector bpv;
endgroup;

Declarations within a macro definition are automatically contained in a group,
so the problem had to do with grouping.

An `Id_Map_Type' object is created for each group and placed onto a stack.  When
it's popped from the stack, the objects on it are destroyed.  Code in
|Id_Map_Entry_Type::~Id_Map_Entry_Type| was causing objects belonging to
vector-type variables to be deleted twice.

I had been getting this error message from `glibc' before at the end of a run, but it
hadn't been causing segmentation faults.  When groups were used, I did get them.

The current sample code performs the following actions:

1.  Draw points and paths representing
    a focus f0 and its plane of projection along with a circle c0
    that lies in the x-z plane.

2.  Take points on c0 and finds their projections
    on the plane of projection for f0.

3.  Create a conic_section_lattice k using
    the projections of the points on c0.

4.  Traverse k to find points on the ellipse e that
    represents the projection of c0 on the plane of projection
    for f0.

The next step will be to find the parameters of e
and create a corresponding object of type `ellipse'.

I have already tested this procedure by writing a prototype
using 3DLDF.  The sample is in `sample0.ldf' or `sample1.ldf'.
I now need to go back to the C++ function
`Conic_Section_Lattice::get_ellipse', which already exists,
and get it to work.  It will require a considerable amount
of error-handling code, which wasn't needed in the prototype.

Rotating objects.

Adding special rules for rotating focuses has made it necessary
to add individual rules for rotating objects of other types.
In the past, this was done by two rules which used the
non-terminal symbol `any_variable'.  (This symbol is used
in the code for the GNU Bison grammar and has no
corresponding type in the 3DLDF language.)

I would like to get rid of the `any_variable' symbol anyway,
but it still works for the other transformation commands
(i.e., other than `rotate'), so I'm keeping it for the present.

PLEASE NOTE:  User code may fail if it tries to rotate an object of
a type using the `rotate' command for which I haven't added rules.
I don't think I missed any drawable types, but if I did, please send
an email to me at `lfinsto1 --AT-- gwdg.de'.  (" --AT-- " stands for "@").

The current sample code draws points and paths representing
a focus f0 and its plane of projection along with a circle c0
that lies in the x-z plane.
It then takes points on c0 and finds their projections
on the plane of projection for f0.  The points representing
the projections are put onto the path q1.

The plane of projection belonging to f0 is represented by the
rectangle r0.
Figure 1 is output using another focus, f1,
which is located behind f0, but with the same direction.
This makes it possible to draw the objects which represent f0.
Figure 2 is output using f0 itself.
Figure 3 is output using a different focus, which makes it
possible to see the objects represent f0 from the side, along with
c0.
Making this example has turned out to be trickier than expected.

The next step will be to create a conic_section_lattice using
the points on q1.
