f16d970f77 textrender: Don't calculate caps on every buffer
Only renegotiate with downstream when the srcpad has a pending
reconfigure flag, instead of querying, fixating and sending caps
for every buffer.

212c94312e textrender: Fix AYUV output.
Fix the check for whether the element is operating in ARGB mode. It
was incorrectly checking if the output format has an alpha channel,
which is true for both ARGB and AYUV, leading to the element
incorrectly outputting ARGB values into AYUV caps.

37c996dcf4 clockoverlay: fix bogus time display caused by previous commit
Fixes regression introduced by "clean-up" done as part of commit 98ebcb4.

dummy must live as long as use the return value of localtime_r() since
that's just a pointer to it, and by putting it inside the block we made
dummy go out of scope right after localtime_r() returned, which messed
up the time values since when we poked at the struct the contents might
already have been overwritten.

Fixes #722

2ace14f613 pango: Create one context per instance and remove class mutex
PangoCairo is thread-safe as long as the context and fontmap are not
shared between threads. Previously each subclass had its own context and
a class mutex for this reason, but apart from hurting performance this
was also not completely safe yet: the same fontmap might've been used by
different classes from different threads as the thread-default fontmap
(at time of class initialization) was used.

5c4f4ac1bd 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.

8a443784c4 basetextoverlay: Add new properties and alignment type for unclamped absolute positions
Introduces [x-absolute, y-absolute] properties
for positioning in +/- MAX_DOUBLE range.

Adds new (h/v)alignment type "absolute" where coordinates
map the text area to be exactly inside of video canvas for [0, 0] - [1, 1]:

[0, 0]: Top-Lefts of video and text are aligned
[0.5, 0.5]: Centers are aligned
[1, 1]: Bottom-Rights are aligned

5830db7050 textoverlay: Query downstream caps for checking if caps features are supported, not just accept-caps
accept-caps is not recursive and might stop at the next downstream element,
while caps queries are generally recursive. The next element might accept any
capsfeatures we want, but that doesn't mean that further downstream it will
also work.

Additionally for the future:
We should probably check if downstream *prefers* the
overlay meta, and only enforce usage of it if we can't handle
the format ourselves and thus would have to drop the overlays.
Otherwise we should prefer what downstream wants here.

d4759f05f1 basetextoverlay: Use the extents rectangle for positioning
the extents rectangle is what you need to know to properly position
a buffer that has been rendered in a surface of the ink rectangle
size. This patch make the placement on par with the placement we had
before without having to over allocate.

This patch also enable placement for vertical rendering. Note that
the halginement, valighment and line-alignment default are set to
the previous default when this property is set. This is for backward
compatibility, you can change the value after setting vertical render.

7569a2e932 basetextoverlay: Fix clipping issues
This patch uses the ink rectangle in order to compute the size
of the surface require to render. It also correctly compute the
transformation matrix as the ink_rect position might not be at
0, 0. Additionally, shadow_offset and outline_offset (which is
in fact the diameter of a dot, not a really an offset) is now
taken into account. Redundant matrix operation has been removed
for the vertical rendering.

Take note that the matrix operation in cairo are excuted in
reverse order.
