Changes from 4.9.12 to 4.9.13 (August 2009)
*******************************************

The main developers this time were: Trent Gamblin, Elias Pschernig,
Paul Suntsov, Peter Wang. Other contributions from: Todd Cope, Evert
Glebbeek, Michael Harrington, Matthew Leverton.

Ports:

* Trent Gamblin started a port to the GP2X Wiz handheld console.

Graphics:

* Some OpenGL bitmap routines were not checking whether the target
bitmap was locked.

* Scaled bitmap drawer was not setting the blend mode.

* Fixed a bug where al_map_rgb followed by al_unmap_rgb would return
different values.

* Fixed problems with sub-sub-bitmaps.

* Fixed window placement on OS X, which did not properly translate
the coordinates specified by the user with
al_set_new_window_position().

* Made is_wgl_extension_supported() fail gracefuly.

* Added ALLEGRO_ALPHA_TEST bitmap flag.

* Minor optimizations in some memory blitting routines.

Input:

* Replaced (ALLEGRO_EVENT_SOURCE *) casting with type-safe
functions, namely al_get_keyboard_event_source,
al_get_mouse_event_source, al_get_joystick_event_source,
al_get_display_event_source, al_get_timer_event_source, etc.

* Made it so that users can derive their own structures from
ALLEGRO_EVENT_SOURCE. al_create_user_event_source() is replaced by
al_init_user_event_source().

* Fixed a problem on Windows where the joystick never regains focus
when tabbing away from a window.

* Fixed a problem with missing key repeat with broken X.Org drivers.

* Implemented ALLEGRO_EVENT_MOUSE_ENTER_DISPLAY,
ALLEGRO_EVENT_MOUSE_LEAVE_DISPLAY for X11.

Image I/O addon:

* Changed return type of al_save_bitmap() to bool.

* Separated al_add_image_handler into al_register_bitmap_loader,
al_register_bitmap_saver, etc.

* Made JPEG and PNG loaders handle al_create_bitmap() failing.

* Speed up JPEG loading and saving.

* Fixed a reinitialisation issue in iio.

Audio addons:

* Moved basic sample loading/saving routines to kcm_audio from
acodec and added file type registration functions.

* Moved WAV support into kcm_audio.

* Made WAV loader not choke on extra chunks in the wave.

* Separated acodec into a5_flac, a5_vorbis addons. You need to
initialise them explicitly. Removed sndfile support.

* Renamed al_*_oggvorbis to al_*_ogg_vorbis.

* Changed argument order in al_save_sample and al_stream_from_file.

* Reordered parameters in al_attach_* functions to follow the word
order.

* Renamed a few streaming functions to refer to fragments/buffers as
fragments consistently.

* Added missing getters for ALLEGRO_SAMPLE fields.

* Fixed mutex locking problems with kcm_audio objects.

* Avoid underfilling a stream when it is fed with a short looping
stream.

Other addons:

* Added glyph advance caching for the TTF addon.

* Renamed al_register_font_extension to al_register_font_loader.
Match the file name extension case insensitively.

Documentation:

* Lots of documentation updates.

* Added a short "Getting started guide" to the reference manual.

Examples:

* Added another example for kcm_audio streaming: ex_synth.

Build system:

* Fix pkg-config .pc files generated for static linking.

* DLL symbols are now exported by name, not ordinals.
