[cairo] CAIRO_FORMAT_A8 / stride

[Nikolaj Thygesen]

Howdy list,

    I'm new to Cairo and this list, and I'm currently doing a graphics gtk+ 
application in which I want to render text to a Cairo 
CAIRO_FORMAT_A8/image_surface using Pango. Now I'm wondering whether it's a 
feature or a bug, when stride insists on being a multiple of four even when 
using CAIRO_FORMAT_A8 == one byte / pixel??? It looks like the rendering 
chops off the two least significant bits of the stride, but I've found no 
documents documenting this "feature", which seems odd to me.
