[cairo] Rendering with PANGO_GRAVITY_EAST leads to different results with image and vectoriel buffer (pdf)

[Behdad Esfahbod]

Hi,

Renders fine here.  Though, with a bitmap font.  Can you attach the resulting 
PDF file?

Better yet, file a bug at http://bugs.freedesktop.org/ against cairo and 
attach it there such that it's not lost.
