Fix wxGTK1 build after wxFont API changes

Browse Source 
Implement the new {Get,Set}{FractionalPointSize,NumericWeight} methods.

Also change wxLoadQueryFont() to use wxNativeFontInfo methods as a side
effect, to reduce code duplication and reuse the existing support for
numeric weights and fractional point sizes in wxNativeFontInfo.
