In directory usw-pr-cvs1:/tmp/cvs-serv10160

Modified Files:
	plot3d.c 
Log Message:
AWI for Gary Bishop.

Fix for long-standing "missing triangles" bug that has been messing up our
3d shaded plots.  Example 8 looks really sharp now.  Kudos to Gary for fixing
this!

Note, the old code has just been dropped by the appropriate #if 0.  But it
should be ripped out completely once we have lived with these changes for a
while.

Modified Files:
	plot3d.c 
Log Message:
AWI for Gary Bishop.

Now make calls from shade_triangle (called by new plotsh3d) to plP_fill
through the clipping interface. (Gives much more meaningful result if the
plot is poorly scaled and thus there is a better chance that the user will
recognize the scaling problem and solve it.)

Tweak plotsh3d documentation.

Refine the #if WANT_MISSING_TRIANGLES (heh) logic that define the old code
that is going to be removed after a while.

Modified Files:

Log Message:
Convert to clipping interface for plfill3.  This remains untested by our
examples so users should beware of the plfill3 code in general.

Code tweak: Change from short to PLINT for xpoly and ypoly in plfill3 to be 
consistent with change from direct call to plP_plfclp to indirect call using

Modified Files:

Log Message:
AWI for Gary Bishop.

Changes to implement 3D clipping for plfill3.  Note the current examples
do not test plfill3 or this change so it is in a state of "should work".

Modified Files:
	plsym.c plline.c 
Log Message:
AWI for Gary Bishop.

Implement 3D clipping for plpoin3 and plline3.  Both of these now work
nicely if you expand the scale of pages [5-8] of the 18th example. However,
equivalent plpoly3 changes are still in the works so the first 4 pages of
example 18th with expanded scale do not 3D clip properly yet.

Implement 3D clipping for plot3d and plotsh3d.  The results look quite
good for an expanded version of the 8th example.

Implement 3D clipping for plpoly3.  This is the last of the 3D clipping work,
and a test with an expanded example 18 looked good.

Fix long-standing bug in plot3d that Gary spotted.  Only a few lines are
involved in the change.  AWI doesn't follow all of this change except that
the u array was being accessed out of its range for one particular case in
the old version.

In directory usw-pr-cvs1:/tmp/cvs-serv30842

Modified Files:
	plot3d.c 
Log Message:
Sort out some minor memory management problems found by valgrind.

plotsh3d: initialize nsub to zero. valgrind detected that this uninitialized
value propagated to pldtik and was used there, but there were no practical
consequences because the returned value was ignored in whatever case.

plnxtvhi_draw:  replace

ptold = ((oldhiview[2 * i] < u[j] && i < mhi) || j >= n);

by

ptold = (j >= n || (i < mhi && oldhiview[2 * i] < u[j]));

the result is the same, but the rearranged order insures no read access
outside of oldhiview and u (which was being detected by valgrind).

Update of /cvsroot/plplot/plplot/src
In directory usw-pr-cvs1:/tmp/cvs-serv7377

Added Files:
	plfreetype.c 
Log Message:
Support routines for drivers interested in using freetype# rendered fonts
instead of plplot plotter fonts.

Any bitmap driver should be able to use any of these freetype fonts from
plplot if these routines are properly initialised.

Freetype support is not intended to be a "feature" of the common API, but
is  implemented as a driver-specific optional extra invoked via the -drvopt
command line toggle. It is intended to be used in the context of
"PLESC_HAS_TEXT" for any bitmap drivers without native font support.
Implementing freetype in this manner minimise changes to the overall API.
Because of this approach, there is not a "wealth" of font options available
to the programmer. You can not do anything you can't do for a normal
freetype plotter font like boldface. You can do most of the things that you
can do with a plotter font however, like greek characters superscripting,
and selecting one of the four "pre-defined" plplot font types. 

Freetype support is turned on/off at compile time by defining
"HAVE_FREETYPE".

[# Freetype is a well known opensource library that supports a gerth of
font formats including TrueType, OpenType, Adobe Type1, Type42 etc... the
list seems almost endless.]

Modified Files:
	plpage.c 
Log Message:
Make plGetCursor() return the subwindow (alias subpage) number.

This might not give the expected result on all plots, if several subwindows and
viewports are set.
Also, for real multi-window (frames) apps, the user must use plgstr() to get
the current stream number, as the subwindow number is set to 0 for each new stream.
