* Notes: There are some known issues that should be corrected.
* - Incorrect foreground text color appears on an active window in OS/2 J1.3.
* - BitBlt's text drawing function does not work correctly.
* - Glitches some part of graphics on the Control Panel in OS/2 J2.1 beta.
* - The screen resolution and blanking interval time maybe not correct.
*
* The code should be tested with following cases.
