Fix mouse warping on OS X.
Fix mouse warping in Linux evdev mouse driver.
pulseaudio: Use smaller buffer size by default, and make it configurable.

Implement al_color_html_to_rgb and al_color_html more strictly.
Delete stride-less version of al_draw_polyline*.

Changes from 5.1.5 to 5.1.6 (March 2013)
The main developers this time were: Trent Gamblin, Paul Suntsov, Peter Wang.
Fix use of clobbered return value from setlocale() on X11.
Register system interface even if no display driver available on Windows.
Fix use of double math functions for float arguments (Nick Trout).
Revamped shader API. The shader API is now part of the core library, and the shader addon removed.
Shaders are now a per-bitmap property, set with al_use_shader. A bitmap without a set shader uses a default shader internally, that allows Allegro drawing functions to work as in non-programmable pipeline mode.
Shader variable setters operate on the shader of the target bitmap.
Rename ALLEGRO_USE_PROGRAMMABLE_PIPELINE to ALLEGRO_PROGRAMMABLE_PIPELINE.
Rename al_link_shader to al_build_shader.

Remove al_get_opengl_program_object, al_set_opengl_program_object, al_get_direct3d_effect, al_set_direct3d_effect.

Add macros for shader variable names (Jon Rafkind).
Made al_get_display_mode return the closest thing to a pixel format possible with the WGL driver (tobing).
Move WGL context destruction out of the message pump thread and into the user/main thread.
Allow command-tab to work in fullscreen window mode on OS X.
Remove "user_reload" parameter from al_acknowledge_drawing_resume.
Don't crash in al_create_display if there is no display driver.
Don't crash at shutdown if there is no display driver (Windows).
Don't fail init if both D3D, GL drivers unavailable (Windows).
Sync bitmaps before resizing display to prevent changes being lost after the resize (D3D).
Load the D3D9X module during display creation and unload it when the D3D system shuts down.
Run fullscreen toggle on main thread (OS X).
Destroy the backbuffer bitmap when destroying the display (OS X).
Switch to new NSTrackingArea API (OS X).
Set ALLEGRO_NO_PRESERVE_TEXTURE on backbuffer (OpenGL).
Let al_destroy_bitmap implicitly untarget the bitmap on the calling thread.

Use memory bitmap drawing when either bitmap is locked (OpenGL).
Fix a crash in D3D destroying sub-bitmaps.
Add const qualifiers to glUniform*v() functions (Aaron Bolyard).
Partially fix mouse buttons "sticking" on Mac, e.g. holding the mouse and toggling fullscreen window.
al_set_mouse_xy on Windows resulted in the mouse getting set to the wrong position in windowed modes
Scale the user supplied mouse cursor if it's too big (Windows).
Add key constants for some Android keys, those that are used in Xperia Play controls.
Fix PulseAudio driver trying to connect to a non-existent server forever.
Avoid memory leaks with audio event source.
Use smaller buffer size for OpenSL.
- Use Allegro built-in loaders in preference to OS X loaders for BMP/TGA/PCX. The OS X TGA loader doesn't support alpha and this is also more consistent.

Fix a few incorrect usages of al_lock_vertex_buffer
Disallow 3 component vectors for ALLEGRO_PRIM_TEX_COORD.
Add a whole bunch of new ALLEGRO_PRIM_STORAGE values.
Primitives addon was ignoring the filter settings of textures in the D3D backend.
Generate KEY_CHAR on Android.
Add key constants for Android.
Set target bitmap to display backuffer after program is resumed.
Use different functions for OpenGL ES 1 and OpenGL ES 2 on Android.
Support stencil buffer on iOS.
Remove unnecessary autorelease pools. There was a crash when using Airplay that goes away without the pools.

Don't autorotate displays other than device.
Fix some threading and memory issues.
Raspberry Pi port:
Allow for color size, depth and stencil sizes.
Support al_show_mouse_cursor and al_hide_mouse_cursor. Disabled as it sometimes ends up stuck on the screen until reboot.

Respect ALLEGRO_FRAMELESS flag properly when toggling from fullscreen window state to windowed state (Windows).
Don't generate DISPLAY_LOST events when resizing a fullscreen display.
Fix al_set/get_window position on Windows so getting/setting to the same position continuosly doesn't move the window. (Michael Swiger)
Rename al_change_display_option to al_set_display_option.
Add al_set_display_icons (plural), implemented for X11 and Windows.
Add ALLEGRO_GTK_TOPLEVEL display flag for X11.
Fix window resizing when using shaders (X11).
Avoid null pointer dereference when setting a target bitmap after its video_texture has already been released (D3D).
Make d3d_lock_region fail immediately if ald3d_sync_bitmap failed, likely because the device was lost.
Set device_lost flag immediately when d3d_display_thread_proc finds the device is lost.
Fix OpenGL extensions being completely ignored on OS X.
Added a quick hack to fix bitmap locking on desktop OpenGL when using shaders.
- Added al_remove_config_key and al_remove_config_section functions.

Make sure stat mode bits are cleared in default implementation of al_update_fs_entry.
Support Unicode paths on Windows.

Fixed loading interlaced .png files with libpng.
Native dialogs addon:
Do not unload of rich edit module when closing one text log window while another exists. Reported by URB753.
Use default colours for Windows text log implementation, avoiding problems when the previous custom colours failed, leading to black text on a nearly black background.
