State code for customizing the font smoothing and cleartype settings.
WINBOM.INI [ComputerSettings] FontSmoothing = ; Default is 'Standard'.
Standard | ; Will determine, based on the system speed, if font ; smoothing is turned on or not.
On | ; Forces font smoothing on. Should only be used if the ; performance of the video card is known to give an ; acceptable user experience with this option enabled.
Off | ; Forces font smoothing off.
ClearType ; Turns clear type and font smoothing on. Should only be ; used if the monitor is known to be an LCD screen and ; that the system performance is known to be acceptable ; with this option enabled.
04/2001 - Jason Cohen (JCOHEN) Added source file for the state that customizes the font and cleartype settings.
