TODO
`uiControl` is an opaque type that describes a control.
`uiControl()` is a conversion macro for casting a pointer of a specific control type (or a `void *`) to `uiControl` while also checking for errors.
`uiControlType()` is the type identifier of a `uiControl` as passed to `uiControlCheckType()`. You rarely need to call this directly; the `uiControl()` conversion macro does this for you.
