[scribus] updating positions by editing positions

[Gary Dale]

One of the things I hate about Scribus is that it seems to duplicate 
styles on a whim. In one document I'm currently working on, it created 
40 copies of the styles. One of the things I like about it is that I can 
fix this with a text editor by removing the duplicated styles directly 
then saving the file. This is a lot faster than removing them using the 
style delete dialogue.

I have a document that I need to make multiple changes to the positions 
and widths of numerous text objects - the same changes for each of 
hundreds of objects that I could presumably do directly by editing the 
.sla file. However when I look at the object positions, the numbers 
don't make sense.

For example, a 136mm x 7mm text object that is located 9mm from the left 
margin and 7mm from the top of the page shows as XPOS="125.512611023622" 
YPOS="1343.85051968504" WIDTH="385.511811023622" HEIGHT="19.8425196850394".

Another 24mm x 28mm object 5mm lower shows as XPOS="125.512611023622" 
YPOS="1358.0237480315" WIDTH="68.0314960629921" HEIGHT="79.3700787401575".

 From the width & height, and the offset for the second object, it 
appears that the internal unit is around 0.3mm but where do the XPOS and 
YPOS numbers come from?
