Excellent! Much, much better! This has taken a weight off my mind.

Hard coded as follows;
cairo_surface_set_fallback_resolution (surface, (x_dpi/72.0) * 300, (y_dpi/72.0) * 300);

Spool for HP Colour PS3 is 26Mb and looks good
Spool for Apple Colour PS2 is 25.5Mb and looks good
Spool for Lexmark Grayscale PS3 is 2.24Mb and looks good - on paper this looks equivalent to 0.45. In fact the contrast is better in 0.46 and there is a slight banding in the 0.45 gradients that isn't there in 0.46

So now, I will resubmit the patch with the fallback bit commented out (with some explanatory stuff), and we will have to talk to Ishmal about cairo again, and hope it makes it in, or at least co-ordinate the fix against the cairo build.

Just need to sort two more things and I'll be really happy;
* Blur scaling and alignment
* Masks
