Non-uniform scaling preview.

["Marcel Toele" <dpy dia gmail com>]

Hi guys,

there are still a few little details to be resolved, but I've managed to put the non-uniform 
scaling into dia custom shapes without too many code changes.

Basically, you write a dia .shape file as you normally would, but I've added a few
attributes to the "dia" namespace (which is virtual, because nobody uses the schemas anyway).

What you could end up with, is a shape file that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns="http://www.daa.com.au/~james/dia-shape-ns"
       xmlns:dia=" http://www.daa.com.au/~james/dia-shape-ns" xmlns:svg="http://www.w3.org/2000/svg">
  <name>Test - Subshape2</name>
  <icon>Subshape2.png</icon>

  <aspectratio type="free"/>

  <svg:svg>

    <svg:rect
     style="fill:#47caf3;fill-opacity:1;stroke:black;stroke-width:0.1;stroke-miterlimit:4;stroke-opacity:1"
     id="rect1874"
     width="12"
     height="9"
     x="0.078606814"
     y="0.062494233 " />

    <svg:g

     dia:v_anchor="fixed.top"
     dia:h_anchor="fixed.right"
     dia:default_scale="1.0"

</shape>

Now obviously, this is mostly just an ordinary .shape file, however two groups (indicated in blue, (for those of you supporting html)), have a special meaning, because of the presence of a few special attributes from the above mentioned "dia" namespace. Their meaning is hopefully self-explanatory.

As I've said earlier, there are still a few issues left, but a preview movie (flash) of the current state of the art can be watched:
