Patch by Andre Moreira Magalhaes <andre.magalhaes@collabora.co.uk> on 2013-08-27
Reviewed by Philippe Normand.

Source/WebCore:

GStreamer source element may be created by any gstreamer element on any thread by calling
gst_element_make_from_uri with the URIs handled by the source element.
This patch makes sure the gstreamer source element is thread-safe to avoid issues with it
being created outside the main thread.

[GTK] Missing DRT AccessibilityUIElement::addNotificationListener implementation
https://bugs.webkit.org/show_bug.cgi?id=119883

Tools:

Implemented the notification listener for AccessibilityUIElement. The signal is generated
by AXObjectCache::postPlatformNotification() and received by axObjectEventListener().
axObjectEventListener will then invoke JSObjectCallAsFunction() with the respective
callback function. The global callback function and callbacks for specific elements are
stored in a HashMap in AccessibilityCallbacksAtk.cpp.

[BlackBerry] Rotate device from landscape to portrait during youtube streaming will cause device screen flash with video list page
https://bugs.webkit.org/show_bug.cgi?id=120364

Patch by Jacky Jiang <zhajiang@blackberry.com> on 2013-08-27
Reviewed by Rob Buis.
Internally reviewed by Arvid Nilsson.

Source/WebCore:

JIRA 461232
When rotating device from landscape mode to portrait mode, we updated
texture contents based on landscape mode front visibility and back
visibility on WebKit thread at the very beginning and the landscape mode
tiles wouldn't be able to cover the portrait mode screen which resulted
in the screen flash.
It's hard to compute front visibility information on WebKit thread because
it doesn't know where the layers will be on the screen. Therefore, the
front visibility won't be updated until the first time we draw textures
on compositing thread.
The patch traverses through LayerWebKitThread and LayerCompositingThread
and discards back visibility and front visibility respectively if there
is a pending orientation. In this way, we can pick up layerTilerPrefillRect
as visibleRect instead of the visibleRect from the stale visibilities
and add more tiles for uncovered screen when updating texture contents
on WebKit thread.
The patch also fixes a bug that we prune tiles based on the stale
m_requiredTextureSize in pruneTextures(). We should prune tiles based
on the updated pendingTextureSize instead.

The offsetTop and offsetLeft of sections, rows and cells should include the table's border. There are separate
problems with the offset[Top|Left] of table sections and the offsetLeft of rows which are covered under bugs 119020
and 119021 respectively - here we stick to just fixing the inclusion of the border as it doesn't require rebaselining
a lot of tests.
