[PATCH v2 0/9] ove Matrix class from libipa to libcamera

[Stefan Klug]

Hi all,

My upcoming dewarper series implements parametric lens dewarping inside
the rkisp1 pipeline. That code makes use of the Matrix class but lives
outside of the IPA. I suspect there will be more cases, where a matrix
is of good use inside libcamera.

This series movies the Matrix into libacmera/internal. As that gets
linked to the IPAs anyways, there are no negative effects for the IPAs.

This was tested on an imx8mp, but only compile tested for the
RaspberryPi.

Regards,
Stefan

Changes since v1:
- Split into smaller patches
- Replaced the initializer_list based constructor with a std::vector
  based one to align with Vector
- Dropped the Span based constructor as it is not used anywhere
