/*---------------------------------------------------------------------------
* Set of debugging macros used by the libraries. If the debug flag is
* set, they are turned on depending on the setting of the flag. User code
* can override the default functions called when a check fails, and the
* MGL does this so it can restore the system from graphics mode to display
* an error message. These functions also log information to the
* scitech.log file in the root directory of the hard drive when problems
* show up.
*
* If you set the value of CHECKED to be 2, it will also enable code to
* insert hard coded debugger interrupt into the source code at the line of
* code where the check fail. This is useful if you run the code under a
* debugger as it will break inside the debugger before exiting with a
* failure condition.
*
* Also for code compiled to run under Windows, we also call the
* OutputDebugString function to send the message to the system debugger
* such as Soft-ICE or WDEB386. Hence if you get any non-fatal warnings you
* will see those on the debugger terminal as well as in the log file.
