[libcamera-devel] [PATCH v8 0/8] 2D transforms

[David Plowman]

Hi everyone

Here's version 8 of the 2D transforms, benefitting from the latest
round of reviews from Laurent. Besides a couple of clarifications and
small fixes (discussed in an earlier email) the main changes are to
the BayerFormat class. Here, among other smaller things, I've changed
the "modifiers" to "packing", and added the IPU3 packing type and
formats.

Otherwise the changes have the same format and 8 commits as before.

Thanks and best regards
David
