Improve Gdk Font Handling

-Fix various uninitialized variables
-Make the FontPlatformData::hash method at least a more reliable (I don't know if this will make a good source for the hash...)
-Move destroying of FontPlatformData resources to FontData::platformDestroy

No this comment should be removed. This is from making FontPlatformData copyable by implementing copy c'tor and assignment operator.

I will update the patch

I wouldn't do so many empty lines, but that is a style thing.
Code looks fine.
