Defining them will increase speed but everything
will work if they are not defined.
If you are not using a routine - turn it off using
the appropriate GDISP_HARDWARE_XXXX macro.
Don't bother coding for obvious similar routines if
there is no performance penalty as the emulation software
makes a good job of using similar routines.
