version 2.27.4
  - bump gtk+ requirement to 2.17.3
  - ensure the drawing area has a native X11 window
    With the new client-side-window gtk+ widgets do not always have a
    native window anymore. We need an XID to give to GstXOverlay and embed
    video into the application. This temporarily works around the issue
    forcing a native window. Works around bug 588357
  - use the camera-web icon instead of camera-video
    we are using camera-web in the project logo/icon but camera-video for the
    UI. it is more appropriate to use the camera-web icon as it's a) less
    likely people will use camcorders with cheese b) there is bigger visual
    distinction between camera-photo and camera-web than camera-photo and
    camera-video.
  - manually expose the window if not PLAYING
    Draw a black background if the pipeline is starting up and the overlay
    is still not ready to expose the drawing area.
  - fix broken xoverlay management
    For some reason this went unnoticed for a long time. We were calling
    set_x_overlay right after setting PLAYING state (with no warranty that
    the state change succeeded nor that an overlay was really there). The
    only right way to do this is to wait for prepare-xwindow-id message. It
    worked until now just because we've been extremely lucky.
  - drop url and email handlers
    Drop url and email handlers used in the about dialog since gtk+ 2.17.2
    already provides that functionality built in.
  - drop GEditMessageArea in favor of GtkInfoBar
    Drop GEditMessageArea since it recently entered gtk+. Fixes bug #586545
  - use AM_SILENT_RULES if available, fixes bug #587581
  - Use accessor functions instead direct access, fixes bug #585210
  - remove markup from translatable strings
  - keybindings: add configure checks for needed X11 stuff
    Check for XF86keysym.h availability and add a configure option to
    disable Webcam Button listening. Copied from rhythmbox.
  - add little program to emit fake webcam button events
  - capture webcam buttons
    Listen to XF86Webcam keypresses to capture webcam buttons. Should
    work with every driver that correctly binds the input device to
    KEY_CAMERA events. Fixes bug #521551
  - remove padding from the take_picture button
    Use alignment xscale property instead of padding in the take_picture
    button. Doesn't fix but at least partly works around bug #573301 (the
    button can now grow up and fill the whole free space with no padding
    constraint).
  - sanitize main toolbar structure
    No real change, just some little restructuring of the glade toolbar
    definition to make it easier to hack on.
