I have created the surface with the following code

this->cro_surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32,
width, height);

This shows the text anti aliased.

This shows the text anti aliased too

But `pango-view -t "some text Wv" --backend=ft2` shows just like the
image I am getting using my program. Thats strange. Cause I am using
cairo and output is like ft2??!!
