PATCH: [Bug 19] - font enumeration problems for aliased gdi fonts

[Rafael Kitover <caelum@debian.org>]

This patch fixes the "Invalid Property Value" message box that pops up 
in older visual basic programs on startup when they try to call 
ENUMFONTS on the default "MS Sans Serif" font for example.
