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.

Original commit message from CVS:
* ext/ffmpeg/gstffmpegenc.c: (gst_ffmpegenc_connect):
Fix pad_link function to handle formats that ffmpeg returns
as multiple caps structures.
* gst/videofilter/gstvideofilter.c: (gst_videofilter_chain):
Only complain if source buffer is _smaller_ than expected.
* gst/videoscale/gstvideoscale.c: (gst_videoscale_init),
(gst_videoscale_handle_src_event): Resize navigation events
when passing them upstream.

* gst/videotestsrc/videotestsrc.c:
* gst/videotestsrc/videotestsrc.h:
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.
