Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv11438

Modified Files:
	plcore.c 
Log Message:
Protected the definition of the plGetDrvDir function with #ifdef
ENABLE_DYNDRIVERS. This avoids potential compilation problems with DRV_DIR
not being defined when --disable-dyndrivers is given to configure.

In directory sc8-pr-cvs1:/tmp/cvs-serv18183/src

Modified Files:
	plmap.c 
Log Message:
plmap():  "Revert" to the previous version.
The original code is not clear, to say the least, see the added comments.

In directory sc8-pr-cvs1:/tmp/cvs-serv27346/src

Modified Files:
	plot3d.c 
Log Message:
For the plmesh*(), plot3d*() and plsurf3d() functions, don't use the data z value to scale the mesh/surface color,
use instead the z axis values set by plw3d().

In directory sc8-pr-cvs1:/tmp/cvs-serv23685

Modified Files:
	plmap.c 
Log Message:
Changed the license terms to LGPL (with Wesley Ebisuzaki'a authorization)
and added copyright notices for the people that contributed in the past to
the code in this file.  This makes a nice example of how to change the
licence and copyright notices in PLplot files.

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv7466a/src

Modified Files:
	plot3d.c 
Log Message:
Replace "bail" error message by something more specific and useful.

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv438

Modified Files:
	plline.c 
Log Message:
Correctly treat the case where one or two corners are encircled by the polygon
fill.  I gave up on this problem 9 years ago but it's actually not that bad.
A good test case: run "x16c -dev tk", zoom in on a smallish region, then start
panning around.  An incorrectly clipped region at one of the corners should
soon appear.  This change fixes most occurances of that.

Still todo: handle the encircling

Exited my editor prematurely.  Still need to handle the case of 3 corners
encircled; also I think the 2 & 4 corner cases aren't quite right yet.

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv31391

Modified Files:
	plline.c 
Log Message:
Many more improvements to fill clipping.  Handle cases where fill polygon
intersects bounding box on two edges by calculating the approximate
circulation of the contour and filling in the edge vertices appropriately.
With these changes the clipping performs accurately up to reasonably high
levels of zooming using x16c as a test case.  At some point (as one continues
to zoom in) it starts to have problems, which I suspect to be a problem in
clipline() or related to fidelity (or both).  Further work on this will have
to wait, as for now I'm out of time.

plstrdup() tcl_cmd string instead of copying the pointer, and remove
(disabled) status from help entry.

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv10958

Modified Files:
	plline.c

Link xwin driver with libpthreads (or if disable dynamic drivers so that
xwin driver embedded in libplplot, link libplplot with libpthreads).

Link libnn with libqhull

Do not link libplplot with libqhull

Do not link libplplot with libpthreads (except for disabled dynamic drivers
case mentioned above and dealt with in the drivers directory).

Log Message:
Update to nn version 1.38

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv22829/src

Modified Files:
	plcore.c plctrl.c 
Log Message:
If the current directory is in the build tree, change files search order so as to load them locally.

The modifications guarantee that files/drivers/scripts are loaded from the build tree if the current
directory is somewhere in the build tree.

The objective is that one should be able to change/test/evaluate PLplot without the necessity of
installing it; recently this was needed (and for some front ends it still is), requiring the user to have a
separate directory to test/change/evaluate PLplot, which means two steps of configure/make, one with
the test --prefix and the other with the final one, which is confusing and error prone. Also, for developpers,
the make/make install step turns the development cycle sloww and boring.

All the compiled front-ends, C, C++ and F77, was tested and work OK with all drivers.
The Tcl and Tk front-ends also work OK, but the tk loadable extensions, Pltk and Plplotter,
as well as the tcl extension Pltcl, still need adjustments in the pkgIndex.tcl script.

The Octave front-end also works OK.

Python and Java was not yet tested.

This is not yet finish, as some problems might yet appear; however, care has been taken to
guarantee that the old behavior still works OK.

tclAPI.c:
   PLbasicInit(): search the init script in the build tree
   pls_auto_path(): add bindings/tk to auto_path

plcore.c:
   add plInBuildTree() that check if the current directory in within the build source tree
   plGetDriverDir(): if in the build tree, load the drivers locally

plctrl.c:
    plFindCommand(): if in the build tree, search locally
    plLibOpenPdfstrm(): if in the build tree, search locally

Update of /cvsroot/plplot/plplot/src

Modified Files:
	plcore.c 
Log Message:
plInBuildTree() is always needed, move out of conditional ENABLE_DYNDRIVERS

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv10611/src

Modified Files:
	pdfutils.c plbox.c plcore.c plfreetype.c plot3d.c 
Log Message:
Mostly cosmetic changes that enable plplot to compiled with (almost) no warnings, even with gcc -Wall.

Most changes are just casts, and most of them are tcl/tk related. For tcl/tk-8.4, no warnings occurs.
Also tested with tcl/tk-8.3, where some warnings remain.
There are no java/f77/cxx/python/octave changes.

Update of /cvsroot/plplot/plplot/src

Modified Files:
	plgridd.c 
Log Message:
Change from int to PLINT arguments for plgriddata to conform to the pattern
for all other functions in our public API.

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv4660

Modified Files:
	plctrl.c 
Log Message:
Fixed debug and error messages.

In function plOpenFile, the message "Opened <filename>" is sent now through
pldebug.  This means that it will not spuriously appear on stderr anymore,
but will be issued when option -debug is specified.  Also, the message
"Can't open <filename>" is sent now to stderr instead of stdout.

In function plLibOpenPdfstr, two calls to pldebug are fixed now (called with
two argments instead of three).

Modified Files:
	plcore.c 
Log Message:
Sane treatment of DATA_DIR and DRV_DIR

The variables/#defines DATA_DIR and DRV_DIR are treated now in a more
coherent and Autotools-friendly way.  The main changes regard:

    - Use of $libdir and $datadir as prefixes of DRV_DIR and DATA_DIR,
      respectively, in configure.ac.  This allows users to easily override
      the installation locations when running configure (options --libdir
      and --datadir).  The environment variables DATA_DIR and DRV_DIR are
      still honored.

    - DRV_DIR is an absolute path now, not relative to DATA_DIR as before.
      Besides it being cleaner and more intuitive, the new design allows
      better compliance with the FHS.  Indeed, architecture-independent
      files (like the font amd map files, as weel as examples and the Tcl
      stuff) go by default in $prefix/share, while driver module files
      (which are architecture-dependent) go in $prefix/lib.

As regards final results, the only difference with the previous situation is
that the *.fnt and *.map files are installed now in plplot<version>/ instead
of plplot<version>/data.  I did not try to keep the previous situation
because it would imply in the definition of a new variable/#define.
However, if the other developers have really strong arguments in favor of
it, I will implement that.

	plcore.c 
Log Message:
Call return after two calls to plabort in function plInitDispatchTable. This
prevents a gratuitous segmentation fault when the drivers library cannot be
opened.

Update of /cvsroot/plplot/plplot/src
In directory sc8-pr-cvs1:/tmp/cvs-serv30793

Modified Files:
	plshade.c 
Log Message:
Fixed subtle bug for the corner case when pltr == NULL AND contouring is
wanted.  In this case, plshades is supposed to have the same interpretation
as plshade, that is if pltr == NULL then transform the x and y index ranges
to the ranges xmin to xmax, and ymin to ymax.  Normally, that transformation
was accomplished by simply passing on pltr to plshade to deal with using the
correct transformation.  But a complication arose for pltr == NULL when
plshades was asked to also invoke plcont after its invocations of plshade.
The plcont interpretation of pltr is different, and in fact it must be
specified so the NULL was causing a segfault.  The solution for the case of
pltr == NULL and contouring is to generate the appropriate x and y grids
ranging from xmin to xmax and ymin to ymax on the fly and set up the
invocation of plcont from plshades appropriately.

I copied the ideas for the necessary memory management from other plplot code
and tested the result with valgrind to make sure no memory management issues
have been introduced by this bug fix.
