172d14acef cairooverlay: Optimize premultiplication/unpremultiplication loops
Pull in video frame fields into local variables. Without this the
compiler must assume that they could've changed on every use and read
them from memory again.

This reduces the inner loop from 6 memory reads per pixels to 4, and the
number of writes stays at 3.

10446bd371 cairooverlay: Add overlay as meta to the buffers if we can
This requires that downstream supports it and
draw-on-transparent-surface is enabled.

f1c5a22a7a cairooverlay: Pre-multiply and un-premultiply alpha in case of ARGB32
Cairo expects pre-multiplied alpha, we work on un-premultiplied alpha.

9844bdbf7a cairooverlay: Add property for drawing on a transparent surface and then blending
This allows us to use the GstVideoOverlayComposition API and correctly
handle pre-multiplied alpha, while also only doing the alpha conversion
once instead of twice for the whole frame.

At a later point we can attach the meta to the buffer instead of
blending ourselves if downstream supports that.

8f807477eb meson: Add feature options for all plugins
Checks for GL, Qt5, and C++ are still automagic. FIXMEs have been
added for these so they can be fixed later.

b68d936ae0 Remove plugin specific static build option
Static and dynamic plugins now have the same interface. The standard
--enable-static/--enable-shared toggle are sufficient.

b09f478e80 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

e3dbf9e256 cairo: remove old cairo-based text renderering element
They haven't worked well or at all in a very long time
and were rather bit-rotten, and there's no need for them
any more.

08702be68f cairo: port cairooverlay to 0.11
The other elements are not that interesting now that we're
using pangocairo in the pango plugin, and should probably
just be removed.

38b596337f cairotextoverlay: forward new segment events from the sink to the source
Not doing so will cause buffers to be received by downstream without
a time base set.
We use the same method avimux uses to get access to the event when
collectpads got the sink event function.
