Hey, that's not fair  This problem has nothing to do with Win32Lib, which
is not what your remark implies.

Well a pixel is a pixel, but not all pixels are the same size. The actual
physical size of a pixel depends on the physical capabilities of the display
monitor.

In your program you have used a constant factor that represents a pixel
size. Instead, you have to ask Windows what is the correct factor for the
screen you are currently using and then use that, in conjunction with the
pixel dimensions used by the particular font you are using. As this is a
fairly common requirement, we should include some support for this in the
library. I'll add it to the enhancement list.
