We might not get an exact match for width or height if stepped ranges
are involved.

49ac382b47 video-converter: Implement multi-threaded scaling/conversion 
This adds a property to select the maximum number of threads to use for
conversion and scaling. During processing, each plane is split into
an equal number of consecutive lines that are then processed by each
thread.

During tests, this gave up to 1.8x speedup with 2 threads and up to 3.2x
speedup with 4 threads when converting e.g. 1080p to 4k in v210.

a62c7bd54c Fix use of undeclared core debug category symbols 
libgstreamer currently exports some debug category
symbols GST_CAT_*, but those are not declared in any
public headers.

Some plugins and libgstvideo just use GST_DEBUG_CATEGORY_EXTERN()
to declare and use those, but that's just not right at
all, and it won't work on Windows with MSVC. Instead look
up the categories via the API.

c9cfd0196f video-converter: Change some implicit string enums to real enums 
GST_VIDEO_CONVERTER_OPT_ALPHA_MODE, GST_VIDEO_CONVERTER_OPT_CHROMA_MODE,
GST_VIDEO_CONVERTER_OPT_MATRIX_MODE, GST_VIDEO_CONVERTER_OPT_GAMMA_MODE and
GST_VIDEO_CONVERTER_OPT_PRIMARIES_MODE were G_TYPE_STRING with only a few valid
options. Changed those to real enums.

f85212ed4b videoscale: fix memory leak

7892e1e22f videoscale: fix 4-tap scaling for 64-bpp formats 
Fix invalid memory access caused by broken pointer arithmetic.

If we have a uint16_t *tmpbuf and add n * dest->stride to it, we
skip twice as much as we intended to because dest->stride is in
bytes and not in pixels. This made us write beyond the end of
our allocated temp buffer, and made the unit test crash.

63d1316c0f videoscale: fix negotiation after addition of new formats and methods

need to cater for that in the transform function: we can't
transform formats not supported by the currently-selected
mehod.
