... which generalizes the current listing of white, black, etc.
In particular, also allow specifying alpha channel, and modify
some structures and pattern filling to cater for alpha value as well.
Fixes#624919.
API: GstVideoTestSrc:solid-color
Adds a pattern with out-of-gamut colors in a checkerboard
pattern with in-gamut neighbors. Useful for checking YCbCr->RGB
color matrixing. Correct matrixing and clamping will cause the
checkerboard pattern to be invisible.

Add a zone plate pattern generator based on BBC R&D Report
1978/23 (yeah *that* 1978). Try 'videotestsrc pattern=zone-plate
kx2=20 ky2=20 kt=1'.

Add "colorspec" property, specifying whether to generate BT.601
or BT.709 video. This only affects YCbCr values, not RGB, since
if you're generating a 709 test pattern, presumably you want
709 RGB primaries, not 601. Also add "smpte75" pattern, which
uses 75% colors instead of 100%, since this is often more useful
for testing (and also follows the SMPTE EG-1 guideline).

Add a "blink" pattern. Turn on the pain. Apologies. It's useful
for testing vertical refresh synchronization.

Add a test pattern called "circular", which has concentric
rings with varying radial frequency. The main purpose of this
pattern is to test fidelity loss in a filter or scaler element.
Notably, this pattern is scale invariant, and is optimally viewed
with a width (and height) of 400.

Fix pad_link function to handle formats that ffmpeg returns
as multiple caps structures.

Only complain if source buffer is _smaller_ than expected.

Rewrite many of the buffer painting functions to handle odd
sizes (for many formats, size%4!=0 or size%8!=0). Most have
been verified to work with my video card.
* testsuite/gst-lint: Add check for elements calling
gst_pad_get_caps() instead of gst_pad_get_allowed_caps().
Original commit message from CVS:
Remove all config.h includes from header files, add it to each source file and remove duplicate config.h includes from several source files
Original commit message from CVS:
Caps fixes. Change meaning of parameters to "default" size and
rate. Minor fixes with timestamps. Added 'YUV9', 'YVU9', and 'IYU2'
formats.
Original commit message from CVS:
New mimetypes gone into effect today - this commit changes all old mimetypes over to the new mimetypes spec as described in the previous commit's document. Note: some plugins will break, some pipelines will break, expect HEAD to be broken or at least not 100% working for a few days, but don't forget to report bugs
Original commit message from CVS:
Lots of new goodness. Will negotiate caps and output images in
about 20 different formats. Some code cleanup. Fixed YUV color
values for -I and Q.
