This is a re-base of PR #215 authored by @nstbayless . Main differences are related to the featureflag table, makefile behaviors, and various improvements to unit tests to better handle various potential error conditions. (all things added to main branch, but which create conflicts and required a rebase)
make WANT_TRANSFORM=1
(this is default behavior)The feature is implemented using software logic and should be functioning properly on any/all platforms. It has been enabled by default, and is not expected to cause build errors or runtime issues, but can be disabled per platform with
WANT_TRANSFORM=0
on a case-by-case basis. Performance of the feature, if used extensively, may be a concern depending on target platform.
