fb102419c7 pango: 3rd time's the charm. Fix attribute list handling.
Really really fix attribute list handling by taking a
copy of the original attributes that pango_attr_list_filter
can mutate, but keep the original around intact to restore
later.

bc42d382e2 pango: Don't modify the original attributes list.
Take a copy of the original attributes list instead of just
a ref, since pango_attr_list_filter can remove elements from it.

52056653be pango: pass pre-multiplied alpha to overlay composition directly

and can avoid multiple conversions if the the overlay also supports
pre-multiplied alpha. We should probably also have mapped the
buffer as READWRITE when unpremultiplying.

over to the new API once we depend on glib >= 2.32.

ddce68a5c2 video: More video helper library improvements
Make a new GstVideoFormatinfo structure that contains the specific information
related to a format such as the number of planes, components, subsampling,
pixel stride etc. The result is that we are now able to introduce the concept of
components again in the API.
Use tables to specify the formats and its properties.
Use macros to get information about the video format description.
Move code to set strides, offsets and size into one function.
Remove methods that are not handled with the structures.
Add methods to retrieve pointers and strides to the components in the video.

9ee7398fae pango: Create a new pango context for every subclass

92d10cbb8c pango: Create a new base class for all the elements
This prevents the ugly hack where the text_sink pad template
was only added for textoverlay but not for the subclasses.

Also makes this work with the core change that made
subclasses inherit the templates of their parent class.

e2150b11ff textoverlay: converted AYUV to use 'A OVER B' alpha compositing
'A OVER B' compositing is explained at
http://en.wikipedia.org/wiki/Alpha_compositing.

Previously, overlaying text on a transparent background image left the
text overlay also transparent. This pipeline shows such an example:

gst-launch videotestsrc pattern=white ! video/x-raw-yuv,format=\(fourcc\)AYUV ! alpha alpha=0.0 ! textoverlay text=Testing auto-resize=False font-desc=60px ! videomixer ! ffmpegcolorspace ! autovideosink

With this patch, text is composited "OVER" the background image and
thus is visible regardless of the alpha of the background image. The
overlay in the above pipeline works after applying this patch.

9ac74c59db textoverlay: use a class wide mutex to work around pango reentrance issues
Pango is not reentrant. Use a class wide mutex to protect pange use in
gst_text_overlay_render_pangocairo(). This works reliable in contrast to the
hack in my previous commit.

54f4aa28c2 textoverlay: fix Cb/Cr inversion for colored text overlays
In case of odd values for xpos or ypos, the division by two in CbCr
plane would result in an off-by-one error, which in the case of NV12,
NV21, or UYVY would cause inversion of blue and red colors.  (And
would be not so easily noticed for I420 as it would just cause the
chroma to be offset slightly from the luma.)

This patch also fixes a silly typo from the earlier patch which
added NV12 support that broke UYVY support.

6bd90dc0cc clockoverlay: only rerender text if time string has changed
The textoverlay element will rerender the text string whenever
overlay sets the 'need_render' flag to TRUE.  Previously, we
lazily set the flag to TRUE every time the time string was requested.
Now, we save a copy of the previously given string, and only set
'need_render' to TRUE if the string has changed.

In my tests with a 30fps video stream, and a time string including
a seconds field, this change reduced the CPU usage of the clockoverlay
element from 60% to 5%.

Fixes bug #627780.
