+ RECURSION IN THE match() FUNCTION
+
+The match() function is highly recursive. Some regular expressions can cause
+it to recurse thousands of times. I was writing for Unix, so I just let it
+call itself recursively. This uses the stack for saving everything that has
+to be saved for a recursive call. On Unix, the stack can be large, and this
+works fine.
+
+It turns out that on non-Unix systems there are problems with programs that
+use a lot of stack. (This despite the fact that every last chip has oodles
+of memory these days, and techniques for extending the stack have been known
+for decades.) So....
+
+There is a fudge, triggered by defining NO_RECURSE, which avoids recursive
+calls by keeping local variables that need to be preserved in blocks of memory
+obtained from malloc instead instead of on the stack. Macros are used to
+achieve this so that the actual code doesn't look very different to what it
+always used to.

+
+Terminology
+-----------
+
+graph == the parent which contains a set of charts layed out in tabular form
+chart == a rectangular region with axis, titles, and legends, and multiple
+ plots
+plot == a set of drawings, overlapping with a chart with axis assigned
+series == 1 displayable set of data of dimensionality related to its
+ associated plot type
+element == 1 'point' in a series
+
+Mailing lists
+-------------
+
+ There is a no mailing list to discuss only the graphing. For now discussion
+ will be on the Gnumeric list, to subscribe send a mail to:
+
+ gnumeric-list-request at gnome.org
+
+ And in the body of the message write "subscribe"
+
+ An archive of the mailing lists is available in:
+
+ http://www.gnome.org/mailing-lists/archives/gnumeric-list/

+ *
+ * The main computation evaluates near-minimax approximations derived

+ * transportable program uses rational functions that theoretically
+ * approximate the normal distribution function to at least 18
+ * significant decimal digits. The accuracy achieved depends on the
+ * arithmetic system, the compiler, the intrinsic functions, and
+ * proper selection of the machine-dependent constants.

+ * those by W. Fullerton in the FNLIB library and also the
+ * TOMS 542 alorithm of W. Gautschi. It provides comparable
+ * accuracy to those algorithms and is considerably simpler.

+
+ Explanation of machine-dependent constants
+
+ beta = Radix for the floating-point system
+ minexp = Smallest representable power of beta
+ maxexp = Smallest power of beta that overflows
+ it = p = Number of bits (base-beta digits) in the mantissa
+ (significand) of a working precision (floating-point) variable
+ NSIG = Decimal significance desired. Should be set to
+ INT(LOG10(2)*it+1). Setting NSIG lower will result
+ in decreased accuracy while setting NSIG higher will
+ increase CPU time without increasing accuracy. The
+ truncation error is limited to a relative error of
+ T=.5*10^(-NSIG).
+ ENTEN = 10 ^ K, where K is the largest long such that
+ ENTEN is machine-representable in working precision
+ ENSIG = 10 ^ NSIG
+ RTNSIG = 10 ^ (-K) for the smallest long K such that
+ K >= NSIG/4
+ ENMTEN = Smallest ABS(X) such that X/4 does not underflow
+ XINF = Largest positive machine number; approximately beta ^ maxexp
+ == GNUM_MAX (defined in #include <float.h>)
+ SQXMIN = Square root of beta ^ minexp = sqrtgnum(GNUM_MIN)
+
+ EPS = The smallest positive floating-point number such that 1.0+EPS > 1.0
+ = beta ^ (-p) == GNUM_EPSILON
+
+
+ For I :
+
+ EXPARG = Largest working precision argument that the library
+ EXP routine can handle and upper limit on the
+ magnitude of X when IZE=1; approximately LOG(beta ^ maxexp)
+
+ For I and J :
+
+ xlrg_IJ = (was = XLARGE). Upper limit on the magnitude of X (when
+ IZE=2 for I()). Bear in mind that if ABS(X)=N, then at least
+ N iterations of the backward recursion will be executed.
+ The value of 10 ^ 4 is used on every machine.
+
+ For j :
+ XMIN_J = Smallest acceptable argument for RBESY; approximately
+ max(2*beta ^ minexp, 2/XINF), rounded up
+
+ For Y :
+
+ xlrg_Y = (was = XLARGE). Upper bound on X;
+ approximately 1/DEL, because the sine and cosine functions
+ have lost about half of their precision at that point.
+
+ EPS_SINC = Machine number below which singnum(x)/x = 1; approximately SQRT(EPS).
+ THRESH = Lower bound for use of the asymptotic form;
+ approximately AINT(-LOG10(EPS/2.0))+1.0
+
+
+ For K :
+
+ xmax_k = (was = XMAX). Upper limit on the magnitude of X when ize = 1;
+ i.e. maximal x for UNscaled answer.
+
+ Solution to equation:
+ W(X) * (1 -1/8 X + 9/128 X^2) = beta ^ minexp
+ where W(X) = EXP(-X)*SQRT(PI/2X)

+ This routine calculates Bessel functions I_(N+ALPHA) (X)
+ for non-negative argument X, and non-negative order N+ALPHA,
+ with or without exponential scaling.
+
+
+ Explanation of variables in the calling sequence
+
+ X - Non-negative argument for which
+ I's or exponentially scaled I's (I*EXP(-X))
+ are to be calculated. If I's are to be calculated,
+ X must be less than EXPARG_BESS (see bessel.h).
+ ALPHA - Fractional part of order for which
+ I's or exponentially scaled I's (I*EXP(-X)) are
+ to be calculated. 0 <= ALPHA < 1.0.
+ NB - Number of functions to be calculated, NB > 0.
+ The first function calculated is of order ALPHA, and the
+ last is of order (NB - 1 + ALPHA).
+ IZE - Type. IZE = 1 if unscaled I's are to be calculated,
+ = 2 if exponentially scaled I's are to be calculated.
+ BI - Output vector of length NB. If the routine
+ terminates normally (NCALC=NB), the vector BI contains the
+ functions I(ALPHA,X) through I(NB-1+ALPHA,X), or the
+ corresponding exponentially scaled functions.
+ NCALC - Output variable indicating possible errors.
+ Before using the vector BI, the user should check that
+ NCALC=NB, i.e., all orders have been calculated to
+ the desired accuracy. See error returns below.
+
+
+ *******************************************************************
+ *******************************************************************
+
+ Error returns
+
+ In case of an error, NCALC != NB, and not all I's are
+ calculated to the desired accuracy.
+
+ NCALC < 0: An argument is out of range. For example,
+ NB <= 0, IZE is not 1 or 2, or IZE=1 and ABS(X) >= EXPARG_BESS.
+ In this case, the BI-vector is not calculated, and NCALC is
+ set to MIN0(NB,0)-1 so that NCALC != NB.
+
+ NB > NCALC > 0: Not all requested function values could
+ be calculated accurately. This usually occurs because NB is
+ much larger than ABS(X). In this case, BI[N] is calculated
+ to the desired accuracy for N <= NCALC, but precision
+ is lost for NCALC < N <= NB. If BI[N] does not vanish
+ for N > NCALC (because it is too small to be represented),
+ and BI[N]/BI[NCALC] = 10**(-K), then only the first NSIG-K
+ significant figures of BI[N] can be trusted.
+
+
+ Intrinsic functions required are:
+
+ DBLE, EXP, gamma_cody, INT, MAX, MIN, REAL, SQRT

+2003-06-07 Jean Brefort <jean.brefort at ac-dijon.fr>
+
+ * graph/gog-style.c (gog_style_editor) :

+ speed up by using regions rather tha nthe bounding rect of the expose.
+ Thanks to AlexL for pointing out that this will help us when
+ multiple exposes are compressed into 1 event and we do better to
+ clip against the distinct sub regions, than the bounding box of all
+ of them.
+ (gog_control_foocanvas_update) : make life easier and pass the zoom to
+ the renderer.
+
+2003-06-02 Jody Goldberg <jody at gnome.org>

+ the anti-aliasing fuzziness in the libart backend for hairline
+ outlines.
+
+ * graph/gog-chart.c (gog_chart_view_size_allocate) : support
+ positions of NE, NW, SE, SW so that we can handle XL's 'corner'
+ legends.
+
+ * graph/gog-control-foocanvas.c (gog_control_foocanvas_draw) : big
+ speed win. Only draw the piece of the chart that was exposed.
+
+ * graph/gog-plot.c (gog_plot_request_cardinality_update) : we may add
+ a series before assigning to a chart.
+

+
+ * graph/gog-legend.c (gog_legend_view_render) : typo. pad is in Y
+ coordinates.
+
+ * graph/gog-plot.c (role_series_post_add) : adding a series changes
+ the cardinality.
+ (role_series_pre_remove) : ditto.

+ (gog_plot_init) : Make sure cardinailty is initially valid so that we
+ queue an an update request as necessary when it really
+ does change.
+
+ * graph/gog-chart.c (gog_chart_view_size_allocate) : support the

+
+ * graph/gog-guru.c (graph_guru_set_page) : we can't run the
+ typeselector without a chart selected.
+ (cb_graph_guru_add_plot) : the child_added handler already populates
+ things.
+ (cb_find_child_added) : It may happen that something else will add an
+ item while we're editing, and the change of focus may not be
+ welcome, However, it is far more likely that we just added it.
+
+ * graph/gog-object.c (gog_object_is_deletable) : don't let the guru
+ delete the top level graph.
+
