/* 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.

* unsigned long as the first parameter. The easiest way to get this
* is to use:
*
* typedef _my_entry {
* cairo_hash_entry_t base;
* ... Remainder of key and value fields here ..
* } my_entry_t;
*
* which then allows a pointer to my_entry_t to be passed to any of
* the cairo_hash_table functions as follows without requiring a cast:
*
* _cairo_hash_table_insert (hash_table, &my_entry->base);
*
* IMPORTANT: The caller is reponsible for initializing
* my_entry->base.hash with a hash code derived from the key. The
* essential property of the hash code is that keys_equal must never
* return TRUE for two keys that have different hashes. The best hash
* code will reduce the frequency of two keys with the same code for
* which keys_equal returns FALSE.
*
* Which parts of the entry make up the "key" and which part make up
* the value are entirely up to the caller, (as determined by the
* computation going into base.hash as well as the keys_equal
* function). A few of the cairo_hash_table functions accept an entry
* which will be used exclusively as a "key", (indicated by a
* parameter name of key). In these cases, the value-related fields of

/* A cairo_paginated_surface provides a very convenient wrapper that
* is well-suited for doing the analysis common to most surfaces that
* have paginated output, (that is, things directed at printers, or
* for saving content in files such as PostScript or PDF files).
*
* To use the paginated surface, you'll first need to create your
* 'real' surface using _cairo_surface_init and the standard
* cairo_surface_backend_t. Then you also call
* _cairo_paginated_surface_create which takes its own, much simpler,
* cairo_paginated_surface_backend. You are free to return the result
* of _cairo_paginated_surface_create from your public
* cairo_<foo>_surface_create. The paginated backend will be careful
* to not let the user see that they really got a "wrapped"
* surface. See test-paginated-surface.c for a fairly minimal example
* of a paginated-using surface. That should be a reasonable example
* to follow.
*
* What the paginated surface does is first save all drawing
* operations for a page into a meta-surface. Then when the user calls
* cairo_show_page, the paginated surface performs the following
* sequence of operations (using the backend functions passed to
* cairo_paginated_surface_create):
*
* 1. Calls start_page (if non NULL). At this point, it is appropriate
* for the target to emit any page-specific header information into
* its output.
*
* 2. Calls set_paginated_mode with an argument of CAIRO_PAGINATED_MODE_ANALYZE
*
* 3. Replays the meta-surface to the target surface, (with an
* analysis surface inserted between which watches the return value
* from each operation). This analysis stage is used to decide which
* operations will require fallbacks.
*
* 4. Calls set_paginated_mode with an argument of CAIRO_PAGINATED_MODE_RENDER
*
* 5. Replays a subset of the meta-surface operations to the target surface
*
* 6. Replays the remaining operations to an image surface, sets an
* appropriate clip on the target, then paints the resulting image
* surface to the target.
*
* So, the target will see drawing operations during two separate
* stages, (ANALYZE and RENDER). During the ANALYZE phase the target
* should not actually perform any rendering, (for example, if
* performing output to a file, no output should be generated during
* this stage). Instead the drawing functions simply need to return
* CAIRO_STATUS_SUCCESS or CAIRO_INT_STATUS_UNSUPPORTED to indicate
* whether rendering would be supported. And it should do this as
* quickly as possible.
*
* NOTE: The paginated surface layer assumes that the target surface
* is "blank" by default at the beginning of each page, without any
* need for an explicit erasea operation, (as opposed to an image
* surface, for example, which might have uninitialized content
* originally). As such, it optimizes away CLEAR operations that
* happen at the beginning of each page---the target surface will not
* even see these operations.
