-/*
- * BIGFONT extension for sharing font metrics between clients (if possible)

-/* 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).

+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.
