	Angle delta if mode_uv directional.

Detailed Description

Variables related to intra-mode search during inter frame coding.

This is a set of variables used during intra-mode search for inter frames. This includes an histogram of gradient speed features and a cache of uv prediction to avoid repeated search of chroma prediction.
