VERSIONS:
cairo (1.3.12 tagged snapshot)
cairo (1.4.2)
glitz 0.5.2 (cvs - 2006-01-10)
***** NOTE FOR VISUAL C++ 6.0 *****
VC6 is not supported. Please upgrade to VC8.
==== Patches ====
All patches in the cairo tree are surrounded by "MOZILLA_CAIRO_NOT_DEFINED" (which should NOT be defined).
Some specific things:
max-font-size.patch: Clamp freetype font size to 1000 to avoid overflow issues
fbcompose-bandaid.patch: Disable "optimized" code in non-MMX case due to bugs

OR
B) Re-implement the line intersection in a way that avoids all

might be that that there are not meaningful names for all of the

looked at complexity, (both are probably similar and it probably

/* For most cairo objects, the rule for multiple threads is that

* being manipulated from multiple threads without the user ever
* being aware of this, (and in fact, unable to control it).
*
* So, as a special exception, the cairo implementation takes care
* of all locking needed for cairo_scaled_font_t. Most of what is
* in the scaled font is immutable, (which is what allows for the
* sharing in the first place). The things that are modified and
* the locks protecting them are as follows:
*
* 1. The reference count (scaled_font->ref_count)
*
* Modifications to the reference count are protected by the
* _cairo_scaled_font_map_mutex. This is because the reference
* count of a scaled font is intimately related with the font
* map itself, (and the magic holdovers array).
*
* 2. The cache of glyphs (scaled_font->glyphs)
* 3. The backend private data (scaled_font->surface_backend,
* scaled_font->surface_private)
*
* Modifications to these fields are protected with locks on
* scaled_font->mutex in the generic scaled_font code.

/*
* In the radial gradient problem we are given two circles (c₁,r₁) and
* (c₂,r₂) that define the gradient itself. Then, for any point p, we
* must compute the value(s) of t within [0.0, 1.0] representing the
* circle(s) that would color the point.
*
* There are potentially two values of t since the point p can be
* colored by both sides of the circle, (which happens whenever one
* circle is not entirely contained within the other).
*
* If we solve for a value of t that is outside of [0.0, 1.0] then we
* use the extend mode (NONE, REPEAT, REFLECT, or PAD) to map to a
* value within [0.0, 1.0].
*
* Here is an illustration of the problem:
*
* p₂
* p •
* • ╲
* · ╲r₂
* p₁ · ╲
* • θ╲
* ╲ ╌╌•
* ╲r₁ · c₂
* θ╲ ·
* ╌╌•
* c₁
*
* Given (c₁,r₁), (c₂,r₂) and p, we must find an angle θ such that two
* points p₁ and p₂ on the two circles are collinear with p. Then, the
* desired value of t is the ratio of the length of p₁p to the length
* of p₁p₂.
*
* So, we have six unknown values: (p₁x, p₁y), (p₂x, p₂y), θ and t.
* We can also write six equations that constrain the problem:
*
* Point p₁ is a distance r₁ from c₁ at an angle of θ:
*
* 1. p₁x = c₁x + r₁·cos θ
* 2. p₁y = c₁y + r₁·sin θ
*
* Point p₂ is a distance r₂ from c₂ at an angle of θ:
*
* 3. p₂x = c₂x + r2·cos θ
* 4. p₂y = c₂y + r2·sin θ
*
* Point p lies at a fraction t along the line segment p₁p₂:
*
* 5. px = t·p₂x + (1-t)·p₁x
* 6. py = t·p₂y + (1-t)·p₁y
*
* To solve, first subtitute 1-4 into 5 and 6:
*
* px = t·(c₂x + r₂·cos θ) + (1-t)·(c₁x + r₁·cos θ)
* py = t·(c₂y + r₂·sin θ) + (1-t)·(c₁y + r₁·sin θ)
*
* Then solve each for cos θ and sin θ expressed as a function of t:
*
* cos θ = (-(c₂x - c₁x)·t + (px - c₁x)) / ((r₂-r₁)·t + r₁)
* sin θ = (-(c₂y - c₁y)·t + (py - c₁y)) / ((r₂-r₁)·t + r₁)
*
* To simplify this a bit, we define new variables for several of the
* common terms as shown below:
*
* p₂
* p •
* • ╲
* · ┆ ╲r₂
* p₁ · ┆ ╲
* • pdy┆ ╲
* ╲ ┆ •c₂
* ╲r₁ ┆ · ┆
* ╲ ·┆ ┆cdy
* •╌╌╌╌┴╌╌╌╌╌╌╌┘
* c₁ pdx cdx
*
* cdx = (c₂x - c₁x)
* cdy = (c₂y - c₁y)
* dr = r₂-r₁
* pdx = px - c₁x
* pdy = py - c₁y
*
* Note that cdx, cdy, and dr do not depend on point p at all, so can
* be pre-computed for the entire gradient. The simplifed equations
* are now:
*
* cos θ = (-cdx·t + pdx) / (dr·t + r₁)
* sin θ = (-cdy·t + pdy) / (dr·t + r₁)
*
* Finally, to get a single function of t and eliminate the last
* unknown θ, we use the identity sin²θ + cos²θ = 1. First, square
* each equation, (we knew a quadratic was coming since it must be
* possible to obtain two solutions in some cases):
*
* cos²θ = (cdx²t² - 2·cdx·pdx·t + pdx²) / (dr²·t² + 2·r₁·dr·t + r₁²)
* sin²θ = (cdy²t² - 2·cdy·pdy·t + pdy²) / (dr²·t² + 2·r₁·dr·t + r₁²)
*
* Then add both together, set the result equal to 1, and express as a
* standard quadratic equation in t of the form At² + Bt + C = 0
*
* (cdx² + cdy² - dr²)·t² - 2·(cdx·pdx + cdy·pdy + r₁·dr)·t + (pdx² + pdy² - r₁²) = 0
*
* In other words:
*
* A = cdx² + cdy² - dr²
* B = -2·(pdx·cdx + pdy·cdy + r₁·dr)
* C = pdx² + pdy² - r₁²
*
* And again, notice that A does not depend on p, so can be
* precomputed. From here we just use the quadratic formula to solve
* for t:
*
* t = (-2·B ± ⎷(B² - 4·A·C)) / 2·A

added to the dynamic symbol table of the shared library. This prevents
users of the library from knowingly or unknowingly accessing library
internals that may change in future releases. It also allows the
compiler to generate slightly more efficient code in some cases.

a function declaration:

THIS PACKAGE CLAIMS TO SUPPORT.

/* The following macros are used for PLT bypassing. First of all,
you need to have the function prototyped somewhere, say in foo.h:
int foo (int __bar);
If calls to foo within libfoo.so should always go to foo defined
in libfoo.so, then in fooint.h you add:
slim_hidden_proto (foo)
and after the foo function definition:
int foo (int __bar)
{
return __bar;
}
slim_hidden_def (foo);
This works by arranging for the C symbol "foo" to be renamed to
"INT_foo" at the assembly level, which is marked pixman_private.
We then create another symbol at the same address (an alias) with
the C symbol "EXT_foo", which is renamed to "foo" at the assembly
level. */
