   GTAPI.H; Screen drawing, cursor and keyboard routines for text mode
            16-bit and 32-bit MS-DOS, 16-bit and 32-bit OS/2, and 32-bit
            Windows 95/NT applications.

   This module is based on VIDMGR by Andrew Clarke and modified for
   the Harbour project

   GTAPI has been compiled and tested with the following C compilers:

     - Turbo C++ (16-bit) for DOS 3.0
     - Borland C++ (16-bit) for DOS 3.1
     - Borland C++ (16-bit) for DOS 4.5
     - Borland C++ (32-bit) for OS/2 1.0
     - Cygnus GNU C (32-bit) for Windows 95/NT b14.0
     - DJGPP GNU C (32-bit) for DOS 2.0
     - EMX GNU C (32-bit) for OS/2 & DOS 0.9b
     - IBM VisualAge C/C++ 3.0 (32-bit) for OS/2
     - Microsoft C/C++ (16-bit) for OS/2 6.00a
     - Microsoft C/C++ (16-bit) for DOS 8.00c
     - Microsoft Quick C (16-bit) for DOS 2.50
     - Microsoft Visual C/C++ (16-bit) for DOS 1.52
     - Microsoft Visual C/C++ (32-bit) for Windows 95/NT 5.0 and 6.0
     - WATCOM C/C++ (16-bit & 32-bit) for DOS 9.5
     - WATCOM C/C++ (16-bit & 32-bit) for DOS 10.0
     - WATCOM C/C++ (32-bit) for OS/2 10.0
     - WATCOM C/C++ (32-bit) for Windows 95/NT 10.0
     - HI-TECH Pacific C (16-bit) for DOS 7.51
