I added two new methods to GR_Graphic: static
s_getScreenResolution() which is used in ut_units for conversions
from and to pixels, and setStaticScreenResolution(), which is used
to set the resolution returned by the former.
All derived graphic classes that do not have a hardcoded screen
resolution, but rather obtain it from the system have to call the
latter method in their constructor -- I have done this for Win32; on
Unix this is not needed as resolution is hardcoded at 100.
