0001-proresenc-skip-warn-on-incorrect-profile.patch is the
continuation of the first patch: we still encode the alpha with the
incorrect profile (ie no change in behaviour) thereby not overriding
the user decision. If he selected strict conformance and a profile
without alpha, alpha channel coding is skipped.

Second patch 0001-proresenc-force-correct-profile-for-alpha.patch
overrides the profile information. The default profile is
PRORES_PROFILE_STANDARD, maye a PRORES_PROFILE_AUTO could be
introduced to control the behavior of this patch.
