[wxGTK2] gtk+-2.8.0 compatibility. Removed the usage of pango_x_get_context to not depend on a fully deprecated

pangox library, which is not pulled in with gtk+-2.8.0. The pango_x_get_context call was (arguably) making font
drawing on top of a wxDC slightly faster on (especially remote) X11 in case of non-antialiased fonts (I was unable to
find a non-antialiased font that actually returns true for GetNoAntiAliasing()).
