					Filters

An application can, to some extent, filter which physical fonts are examined by the font mapper. 
Aspect-ratio filtering, which is available in both Windows versions 3.0 and 3.1, allows an 
application to specify that only fonts designed for the device's aspect ratio should be considered 
by the font mapper. An application enables and disables this filter by using the SetMapperFlags 
function. Because nonscaling raster fonts are designed with a certain aspect ratio in mind, it is 
sometimes desirable to ensure that only fonts actually designed for the device are used. When this 
filter is enabled, the font mapper does not consider any physical fonts whose design aspect ratio 
does not match that of the device. Aspect-ratio filtering does not affect TrueType fonts because 
they can scale to match any aspect ratio. This filter affects all font selections to the DC until 
the filter is turned off. Aspect-ratio filtering is a holdover from earlier times and is not a 
recommended approach in today's font world.
