I am grateful for your many attempts to understand the issues I raise.
your solution also appears excellent, though the method isn't clear  
to me directly**.

my concern is whether a child can use SVG authoring tools, unaided.
Tuxpaint, iSketch, msPaint and very many other tools already provide  
this facility for raster painting.

A child who can use scissors and paper, and understands the GUI icons  
and method used to represent this process.
A child has much experience of stretchy substances, and does not  
require to understand percentage values.

similarly someone not versed in SVG can understand much by reviewing  
code samples.
however, the representation of holes in an SVG document is perhaps  
more complex than strictly necessary.

the reality that output is frequently accurate to 12 significant  
figures, where 3 or maybe 5 would be sufficient, greatly hinders  
ready comprehension.

It's my contention that to define and create such an authoring tool,  
an SVG specification has to be designed with this in mind.
The evidence being that there isn't such a tool after a decade.

**would a reduced testcase similar to Jeff's help clarify your method?
