GTK: slightly reword a comment to reflect Cairo documentation

Browse Source 
The Cairo documentation is clear that cairo_set_antialias() only
affects shape drawing and not text rendering.  To change
anti-aliasing settings for font rendering you need
cairo_font_options_set_antialias() instead.  Therefore the comment
can be a bit more certain than just describing what Cairo "appears"
to do.
