[cairo] 32k limit with image surface?

[Ian Britten]

Hi all,
Is there a 32k limit to the number of pixels (in a scanline) that
an image surface may contain (ie: Its width)?

I'm pursuing a problem where my rendered image doesn't seem to
contain any data after pixel 32767, and I'm wondering if it's due
to something within the Cairo stack?

I'm currently on 64-bit Mandriva 2008.1, with:
     Cairomm = 1.8.0
     Cairo = 1.8.8
     Pixman = 0.12.0

Many thanks for any info!
Ian
