-/* Define some macros which can expand into proxy functions between
- * ARM assembly optimized functions and the rest of pixman fast path API.
- *
- * All the low level ARM assembly functions have to use ARM EABI
- * calling convention and take up to 8 arguments:
- * width, height, dst, dst_stride, src, src_stride, mask, mask_stride
- *
- * The arguments are ordered with the most important coming first (the
- * first 4 arguments are passed to function in registers, the rest are
- * on stack). The last arguments are optional, for example if the
- * function is not using mask, then 'mask' and 'mask_stride' can be
- * omitted when doing a function call.
- *
- * Arguments 'src' and 'mask' contain either a pointer to the top left
- * pixel of the composited rectangle or a pixel color value depending
- * on the function type. In the case of just a color value (solid source
- * or mask), the corresponding stride argument is unused.

- * There used to be a bug in the X server where it would rely on
- * out-of-bounds accesses when it was asked to composite with a
- * window as the source. It would create a pixman image pointing
- * to some bogus position in memory, but then set a clip region
- * to the position where the actual bits were.
- *
- * Due to a bug in old versions of pixman, where it would not clip
- * against the image bounds when a clip region was set, this would
- * actually work. So when the pixman bug was fixed, a workaround was
- * added to allow certain out-of-bound accesses. This function disabled
- * those workarounds.
- *
- * Since 0.21.2, pixman doesn't do these workarounds anymore, so now
- * this function is a no-op.

- * Implementation of radial gradients following the PDF specification.
- * See section 8.7.4.5.4 Type 3 (Radial) Shadings of the PDF Reference
- * Manual (PDF 32000-1:2008 at the time of this writing).
- *
- * In the radial gradient problem we are given two circles (c₁,r₁) and
- * (c₂,r₂) that define the gradient itself.
- *
- * Mathematically the gradient can be defined as the family of circles
- *
- * ((1-t)·c₁ + t·(c₂), (1-t)·r₁ + t·r₂)
- *
- * excluding those circles whose radius would be < 0. When a point
- * belongs to more than one circle, the one with a bigger t is the only
- * one that contributes to its color. When a point does not belong
- * to any of the circles, it is transparent black, i.e. RGBA (0, 0, 0, 0).
- * Further limitations on the range of values for t are imposed when
- * the gradient is not repeated, namely t must belong to [0,1].
- *
- * The graphical result is the same as drawing the valid (radius > 0)
- * circles with increasing t in [-inf, +inf] (or in [0,1] if the gradient
- * is not repeated) using SOURCE operatior composition.
- *
- * It looks like a cone pointing towards the viewer if the ending circle
- * is smaller than the starting one, a cone pointing inside the page if
- * the starting circle is the smaller one and like a cylinder if they
- * have the same radius.
- *
- * What we actually do is, given the point whose color we are interested
- * in, compute the t values for that point, solving for t in:
- *
- * length((1-t)·c₁ + t·(c₂) - p) = (1-t)·r₁ + t·r₂
- *
- * Let's rewrite it in a simpler way, by defining some auxiliary
- * variables:
- *
- * cd = c₂ - c₁
- * pd = p - c₁
- * dr = r₂ - r₁
- * lenght(t·cd - pd) = r₁ + t·dr
- *
- * which actually means
- *
- * hypot(t·cdx - pdx, t·cdy - pdy) = r₁ + t·dr
- *
- * or
- *
- * ⎷((t·cdx - pdx)² + (t·cdy - pdy)²) = r₁ + t·dr.
- *
- * If we impose (as stated earlier) that r₁ + t·dr >= 0, it becomes:
- *
- * (t·cdx - pdx)² + (t·cdy - pdy)² = (r₁ + t·dr)²
- *
- * where we can actually expand the squares and solve for t:
- *
- * t²cdx² - 2t·cdx·pdx + pdx² + t²cdy² - 2t·cdy·pdy + pdy² =
- * = r₁² + 2·r₁·t·dr + t²·dr²
- *
- * (cdx² + cdy² - dr²)t² - 2(cdx·pdx + cdy·pdy + r₁·dr)t +
- * (pdx² + pdy² - r₁²) = 0
- *
- * A = cdx² + cdy² - dr²
- * B = pdx·cdx + pdy·cdy + r₁·dr
- * C = pdx² + pdy² - r₁²
- * At² - 2Bt + C = 0
- *
- * The solutions (unless the equation degenerates because of A = 0) are:
- *
- * t = (B ± ⎷(B² - A·C)) / A
- *
- * The solution we are going to prefer is the bigger one, unless the
- * radius associated to it is negative (or it falls outside the valid t
- * range).
- *
- * Additional observations (useful for optimizations):
- * A does not depend on p
- *
- * A < 0 <=> one of the two circles completely contains the other one
- * <=> for every p, the radiuses associated with the two t solutions
- * have opposite sign
