7f23e75f3c videoconvert: small cleanups
Make function pointers NULL when nothing needs to be done.
Pass target pixels to dither and matrix functions so that we can later make
them operate on the target buffer memory directly.

aa261162d2 videoconvert: fix offset and scale for GRAY
Fix the calculation of the offset and scale values for GRAY formats. We also
need to set the offset and base of the chroma values to match what the unpack
function creates.

ddce68a5c2 video: More video helper library improvements
Make a new GstVideoFormatinfo structure that contains the specific information
related to a format such as the number of planes, components, subsampling,
pixel stride etc. The result is that we are now able to introduce the concept of
components again in the API.
Use tables to specify the formats and its properties.
Use macros to get information about the video format description.
Move code to set strides, offsets and size into one function.
Remove methods that are not handled with the structures.
Add methods to retrieve pointers and strides to the components in the video.

6d9e76f2de video: remove intermediate Plane structure
Remove the GstVideoPlane structure and move the fields directly into the
GstVideoInfo structure. This makes things a little easier to read and also makes
it more likely that we can pass the stride array to external libraries.
