Adding Transparency/opacity/RGBA to Input fileds e.g createTextField

[heniam]

Hey, I have forked the branch and added a feature for adding RGBA so that we can add transparency to createTextField and all other inputFields. Just wanted to get a feedback on that; if it's possible as when i run my tests it's which borderColor instead of transparent after adding; RGBA functionality similar how rgb and other colors are done. Any feedback in the right direction is appreciated. I just don't want to create a pull request for a feature that is not fully functional yet. Thank you.

It works when applied on adobe but not programatically as seen here.
Left : is transparent border and fill color --- right : rgba implemented and applied but shows as white border and fill color

Thank you,
