static bool Radio(string text, bool active)

string text Text to display on the radio, should be per-window unique as it will be used as the element id.
bool active Does this button look like it’s pressed?
RETURNS: bool Will return true only on the first frame it is pressed!

A Radio is similar to a button, except you can specify if it looks pressed or not regardless of interaction. This can be useful for radio-like behavior! Check an enum for a value, and use that as the ‘active’ state, Then switch to that enum value if Radio returns true.
