Hi,
We have a bunch of functions that create planes properties that will take a default value, but it isn't actually enforced in the plane state.
This leads to drivers having multiple strategies to work around that issue, most of them being a variation of forcing a value at plane state reset time. Others work fine by luck, or have entirely ignored the issue.
This series aims at making sure the default value set by the call to the function isn't ignored, and then making sure all drivers behave consistently.
Let me know what you think, Maxime
