*
* slim_hidden_def(f)
*
* Exports `f' back to the global symbol table. This macro must be
* expanded right after the function definition and only for symbols
* hidden previously with slim_hidden_proto(). The macro works by
* adding a global entry to the symbol table which points at the
* internal name of `f' created by slim_hidden_proto().

/**
* SECTION:cairo-device
* @Title: cairo_device_t
* @Short_Description: interface to underlying rendering system
* @See_Also: #cairo_surface_t
*
* Devices are the abstraction Cairo employs for the rendering system
* used by a #cairo_surface_t. You can get the device of a surface using
* cairo_surface_get_device().
*
* Devices are created using custom functions specific to the rendering
* system you want to use. See the documentation for the surface types
* for those functions.
*
* An important function that devices fulfill is sharing access to the
* rendering system between Cairo and your application. If you want to
* access a device directly that you used to draw to with Cairo, you must
* first call cairo_device_flush() to ensure that Cairo finishes all
* operations on the device and resets it to a clean state.
*
* Cairo also provides the functions cairo_device_acquire() and
* cairo_device_release() to synchronize access to the rendering system
* in a multithreaded environment. This is done internally, but can also
* be used by applications.
*
* Putting this all together, a function that works with devices should
* look something like this:
* <informalexample><programlisting>
* void
* my_device_modifying_function (cairo_device_t *device)
* {
* cairo_status_t status;
*
* // Ensure the device is properly reset
* cairo_device_flush (device);
* // Try to acquire the device
* status = cairo_device_acquire (device);
* if (status != CAIRO_STATUS_SUCCESS) {
* printf ("Failed to acquire the device: %s\n", cairo_status_to_string (status));
* return;
* }
*
* // Do the custom operations on the device here.
* // But do not call any Cairo functions that might acquire devices.
*
* // Release the device when done.
* cairo_device_release (device);
* }
* </programlisting></informalexample>
*
* <note><para>Please refer to the documentation of each backend for
* additional usage requirements, guarantees provided, and
* interactions with existing surface API of the device functions for
* surfaces of that type.
* </para></note>

* Cairo's error handling is designed to be easy to use and safe. All major

* can be queried anytime by the users using cairo*_status() calls. In
* the mean time, it is safe to call all cairo functions normally even if the
