-/*
- * BIGFONT extension for sharing font metrics between clients (if possible)
- * and for transmitting font metrics to clients in a compressed form.

-/* THIS IS NOT AN X CONSORTIUM STANDARD */
-
-/*
- * Big fonts suffer from the following: All clients that have opened a
- * font can access the complete glyph metrics array (the XFontStruct member
- * `per_char') directly, without going through a macro. Moreover these
- * glyph metrics are ink metrics, i.e. are not redundant even for a
- * fixed-width font. For a Unicode font, the size of this array is 768 KB.
- *
- * Problems: 1. It eats a lot of memory in each client. 2. All this glyph
- * metrics data is piped through the socket when the font is opened.
- *
- * This extension addresses these two problems for local clients, by using
- * shared memory. It also addresses the second problem for non-local clients,
- * by compressing the data before transmit by a factor of nearly 6.
- *
- * If you use this extension, your OS ought to nicely support shared memory.
- * This means: Shared memory should be swappable to the swap, and the limits
- * should be high enough (SHMMNI at least 64, SHMMAX at least 768 KB,
- * SHMALL at least 48 MB). It is a plus if your OS allows shmat() calls
- * on segments that have already been marked "removed", because it permits
- * these segments to be cleaned up by the OS if the X server is killed with
- * signal SIGKILL.
- *
- * This extension is transparently exploited by Xlib (functions XQueryFont,
- * XLoadQueryFont).

+
+/* THIS IS NOT AN X CONSORTIUM STANDARD */
+
+/*
+ * Big fonts suffer from the following: All clients that have opened a
+ * font can access the complete glyph metrics array (the XFontStruct member
+ * `per_char') directly, without going through a macro. Moreover these
+ * glyph metrics are ink metrics, i.e. are not redundant even for a
+ * fixed-width font. For a Unicode font, the size of this array is 768 KB.
+ *
+ * Problems: 1. It eats a lot of memory in each client. 2. All this glyph
+ * metrics data is piped through the socket when the font is opened.
+ *
+ * This extension addresses these two problems for local clients, by using
+ * shared memory. It also addresses the second problem for non-local clients,
+ * by compressing the data before transmit by a factor of nearly 6.
+ *
+ * If you use this extension, your OS ought to nicely support shared memory.
+ * This means: Shared memory should be swappable to the swap, and the limits
+ * should be high enough (SHMMNI at least 64, SHMMAX at least 768 KB,
+ * SHMALL at least 48 MB). It is a plus if your OS allows shmat() calls
+ * on segments that have already been marked "removed", because it permits
+ * these segments to be cleaned up by the OS if the X server is killed with
+ * signal SIGKILL.
+ *
+ * This extension is transparently exploited by Xlib (functions XQueryFont,
+ * XLoadQueryFont).

-
-where

-

- * this section computes the x value of the span at y

- * ellipse_x h^2 h^2
- * x = ------------ y + ellipse_x (1 - --- )
- * ellipse_y w^2 w^2

- * 0 = - ----------------------------------
- * h w ellipse_y^2 sqrt (h^2 - ellipse_y^2)

+Three equations combine to describe the boundaries of the arc
+
+x^2/w^2 + y^2/h^2 = 1 ellipse itself
+(X-x)^2 + (Y-y)^2 = r^2 circle at (x, y) on the ellipse
+(Y-y) = (X-x)*w^2*y/(h^2*x) normal at (x, y) on the ellipse
+
+These lead to a quartic relating Y and y
+
+y^4 - (2Y)y^3 + (Y^2 + (h^4 - w^2*r^2)/(w^2 - h^2))y^2
+ - (2Y*h^4/(w^2 - h^2))y + (Y^2*h^4)/(w^2 - h^2) = 0
+
+The reducible cubic obtained from this quartic is
+
+z^3 - (3N)z^2 - 2V = 0
+
+where
+
+N = (Y^2 + (h^4 - w^2*r^2/(w^2 - h^2)))/6
+V = w^2*r^2*Y^2*h^4/(4 *(w^2 - h^2)^2)
+
+Let
+
+t = z - N
+p = -N^2
+q = -N^3 - V
+
+Then we get
+
+t^3 + 3pt + 2q = 0
+
+The discriminant of this cubic is
+
+D = q^2 + p^3
+
+When D > 0, a real root is obtained as
+
+z = N + cbrt(-q+sqrt(D)) + cbrt(-q-sqrt(D))
+
+When D < 0, a real root is obtained as
+
+z = N - 2m*cos(acos(-q/m^3)/3)
+
+where
+
+m = sqrt(|p|) * sign(q)
+
+Given a real root Z of the cubic, the roots of the quartic are the roots
+of the two quadratics
+
+y^2 + ((b+A)/2)y + (Z + (bZ - d)/A) = 0
+
+where
+
+A = +/- sqrt(8Z + b^2 - 4c)
+b, c, d are the cubic, quadratic, and linear coefficients of the quartic
+
+Some experimentation is then required to determine which solutions
+correspond to the inner and outer boundaries.
