d8308d5a8f video-resampler: make sure params.envelope is initialized
In gst_video_resampler_init () if method is GST_VIDEO_RESAMPLER_METHOD_NEAREST

Make sure this variable is initiliazed to avoid undefined behaviour.

23880ec874 video-resampler: remove check for below zero for unsigned value
CLAMP checks both if n_taps is '< 0' and '> max_taps'. n_taps will never be a
negative number because it is an unsigned integer. Removing that check and only
making sure it isn't set bigger than max.

721bbcad34 video-resampler: Fix lanczos parameters for variable taps

7b7270ecff video-resampler: add option to limits taps
Add an option to limit the number of taps to use in automatic mode. The
problem is that for lanczos, we might use more taps than what we can
handle with the current precision.
Rework the other options a little to make it nicer to set defaults.

ca2bd1cc6b video-scaler: rename resampler to video-resampler
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.
