Add support for generation of 10/12/14/16 bit bayer test pattern.
The implementation is rather simplistic, just take the ARGB
input, generate 16-bit data out of it instead of 8-bit, shift
them as required by the output bitness, and apply endian swap.
Example usage:
```
$ gst-launch-1.0 videotestsrc ! \
video/x-bayer,width=512,height=512,format=bggr12le ! \
bayer2rgb ! \
video/x-raw,format=RGBA64_LE ! \
videoconvert ! \
autovideosink
```

* The test pattern to produce.
|
|
*
|
|
* The Gamut pattern creates a checkerboard pattern of colors at the
|
|
* edge of the YCbCr gamut and nearby colors that are out of gamut.
|
|
* The pattern is divided into 4 regions: black, white, red, and blue.
|
|
* After conversion to RGB, the out-of-gamut colors should be converted
|
|
* to the same value as their in-gamut neighbors. If the checkerboard
|
|
* pattern is still visible after conversion, this indicates a faulty
|
|
* conversion. Image manipulation, such as adjusting contrast or
|
|
* brightness, can also cause the pattern to be visible.
|
|
*
|
|
* The Zone Plate pattern is based on BBC R&D Report 1978/23, and can
|
|
* be used to test spatial frequency response of a system. This
|
|
* pattern generator is controlled by the xoffset and yoffset parameters
|
|
* and also by all the parameters starting with 'k'. The default
|
|
* parameters produce a grey pattern. Try 'videotestsrc
|
|
* pattern=zone-plate kx2=20 ky2=20 kt=1' to produce something
|
|
* interesting.
