Avoids one or two dozen unoptimizable string copies and two CPos copies, mostly in SetupText. The reference return allows to mark values as const where the previous one prevented that. This also reveals unused variables where the previous code hid them. Thus use unused variable "buffer_zone" in the otherwise unused (sinceb1422137e5, refs0f807c643a) CCheckBox::SetupText() fromb5f6d19332and use the unused variable "scrollbar" in CInput GUIM_MOUSE_PRESS_LEFT from4113aa0a36. Refs unintentionally copied DrawCall cache due to GetSetting copying inc19f3608a5, fixed in8f4f8e240f. Differential Revision: https://code.wildfiregames.com/D2215 This was SVN commit r22765.
