Change Details

We generally want to use the "disabled hint" more often, which is a red text in tooltips that explains why a button is disabled. So far this can't be done from Python at all. This is a first step to get it supported. This is a low-effort attempt, but I think it's a reasonable way to go about it. To set the hint, in a poll method, Python operators can set it like this: ``` context.operator_poll_message = "Can't do this, because of reasons" return False ``` The string is stored as copy in an allocated buffer. Not sure if this will work with translations though, ie obtaining the string with `IFACE_()`.
