Simulation support:

None. This function is mandatory for all drivers.

Description:

GreDeviceQueryFonts returns the characteristics of device fonts in an array of FONTMETRICS structures, if the QF_PUBLIC option flag (see the flOptions parameter) is set. The returned fonts include those that correspond to device modes such as "expanded" and "expanded-bold".

This function must be supported by the presentation driver.
