* 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.
