/*
 * FONT_INFO
 *
 * The distinction between the desired and actual font dimensions obtained
 * is important in the case of TrueType fonts, in which there is no guarantee
 * that what you ask for is what you will get.
 *
 * Note that the correspondence between "Desired" and "Actual" is broken
 * whenever the user changes his display driver, because GDI uses driver
 * parameters to control the font rasterization.
 *
 * The SizeDesired is {0, 0} if the font is a raster font.
