Mac body: ECX (ESI) is the dialog (+0x34 box width) and EDX is multiplied by 0x110 to index the dialog's line records (+0x68 text, +0x15c X offset, +0x160 width, +0x168 font); it measures the line and stores the centring offset; no stack arguments, plain RET. Windows twin DIALOG_CenterStringLine 0x004b83a0 is void (D2DialogStrc * pDialog, int32_t nIndex); same order on Mac.
