[libcamera-devel] [PATCH v3 02/17] ipa: rkisp1: Rename frameContext to activeState

Quoting Jacopo Mondi via libcamera-devel (2022-08-18 10:43:55)
> From: Kieran Bingham via libcamera-devel <libcamera-devel at lists.libcamera.org>
> 
> Move the existing frame context structure to the IPAActiveState.
> This structure should store the most up to date results for the IPA
> which may be shared to other algorithms that operate on the data.
> 

Laurent queried this patch in v2.

I suggested we add the following to this commit message:

"""
All existing algorithm state is moved to the ActiveState and the
algorithms should be updated individually to use the FrameContext
directly where appropriate.
"""
