Comment 1 for bug 166178

Confirmed with current CVS.
Currently the compensation of stroke-width is in
sp_item_write_transform, which is called only when writing
to the repr. (The functions that sp_item_write_transform
calls tend to call item->updateRepr().)
To provide the desired accurate previewing of stroke width,
I think we'd have a function like the current
sp_item_write_transform except without updating the repr(s).

This bug affects only the preview of the shape while still
being dragged, so I'm assigning a low priority number.

There are a few areas where inkscape delays updating the
display until either an idle event or the mouse is released.
 Typically these are to improve responsiveness with large
drawings. I don't know offhand whether this is such a case.
 Eventually inkscape may become smarter at handling such
cases, though I'd guess people won't look at that for a while.
