-+/* This is the "magic number" approach to converting a double into fixed
-+ * point as described here:
-+ *
-+ * http://www.stereopsis.com/sree/fpu2006.html (an overview)
-+ * http://www.d6.com/users/checker/pdfs/gdmfp.pdf (in detail)
-+ *
-+ * The basic idea is to add a large enough number to the double that the
-+ * literal floating point is moved up to the extent that it forces the
-+ * double's value to be shifted down to the bottom of the mantissa (to make
-+ * room for the large number being added in). Since the mantissa is, at a
-+ * given moment in time, a fixed point integer itself, one can convert a
-+ * float to various fixed point representations by moving around the point
-+ * of a floating point number through arithmetic operations. This behavior
-+ * is reliable on most modern platforms as it is mandated by the IEEE-754
-+ * standard for floating point arithmetic.
-+ *
-+ * For our purposes, a "magic number" must be carefully selected that is
-+ * both large enough to produce the desired point-shifting effect, and also
-+ * has no lower bits in its representation that would interfere with our
-+ * value at the bottom of the mantissa. The magic number is calculated as
-+ * follows:
-+ *
-+ *          (2 ^ (MANTISSA_SIZE - FRACTIONAL_SIZE)) * 1.5
-+ *
-+ * where in our case:
-+ *  - MANTISSA_SIZE for 64-bit doubles is 52
-+ *  - FRACTIONAL_SIZE for 16.16 fixed point is 16
-+ *
-+ * Although this approach provides a very large speedup of this function
-+ * on a wide-array of systems, it does come with two caveats:
-+ *
-+ * 1) It uses banker's rounding as opposed to arithmetic rounding.
-+ * 2) It doesn't function properly if the FPU is in single-precision
-+ *    mode.

-Subject: [PATCH] Add new perf test "pattern_create_radial"
-
-This test is really just for hammering the double to fixed-point conversion
-(in _cairo_fixed_from_double) that happens as doubles from API calls gets
-translated into internal cairo fixed-point numbers.
-
-Because it's not generally useful, I don't recommend that it become part of
-the main cairo performance test. But hey, it might come in handy for someone
-else.
