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.
