Vadim Zeitlin f741031e69 Suppress gcc -Wfloat-conversion warning in wxFontInfo ctor 
Add an explicit cast to avoid warnings when compiling with this option.

While just casting double to float is not the best idea, it seems quite
unlikely that anybody would pass a value outside of float range to this
ctor.
