| <TCXLmou.h> : Definitions and prototypes for TCXL Microsoft-compatible
| mouse functions.
*-------------------------------[ Notes ]------------------------------*
| 1) All mouse positions are in terms of text rows and columns.
| 2) MSinit() and MSterm() MUST not be called by user code. They are
| called by the TCXL initialization and termination functions.
| 3) MSpush() and MSpop() position the mouse cursor.
