f4f3894836 video-scaler: Enforce same taps on Y and UV scalers for merged formats
Make sure we have the same number of taps for the Y and UV scalers so
that the scalers can be merged correctly.

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.

3cd2eb5847 video-converter: fix border handling of YUY2 and friends
Don't draw the border in groups of 4 pixels for YUY2 but instead in
groups of 2 with alternating U and V. This avoids a crash on odd width
borders.

0d333d8d44 video-converter: add table based matrix8 implementation
Based on patch from Mozzhuhin Andrey <nopscmn at gmail.com>

Add a table based matrix8 multiplication implementation. The algorithm
does not do any clipping so we need to make sure we never call this on
input that might need to be clipped. In general, this algorithm is
2 times faster than the orc optimized one and would be chosen for all
RGB -> YUV conversions and some YUV->YUV and RGB->RGB conversions.

number since it in an unsigned integer. Removing that check and only checking

cdd86d025a video-scaler: add 2d scaler
Make a convenience function that combines 2 scalers to perform a 2d
scale. This removes quite a bit of overhead in method calls when doing a
typical scale and it also can reuse a piece of unused memory in the
vertical scaler.
Use the 2d scaler in video-converter and remove the other scalers and
temp memory.
