[Node tool] Scale/stretch/skew transforms with transform handles don't snap

[su_v]

Inkscape 0.47+devel r9486 on OS X 10.5.8, default settings

Steps to reproduce:
1) show grid
2) draw a path
3) switch to node tool, activate 'Show Transform Handles'
4) scale, stretch or skew the selection by dragging a transform handle with the mouse, snapping to the grid

Expected result:
The same as when scaling/skewing with the select tool: (node) snapping happens according to the settings in the snap controls bar.

Actual result:
Snapping is disabled when transforming nodes using the transform handles

Workaround:
None

Probably snapping has never been implemented before for this workflow. I wonder though where in the code base the transformations are calculated; If it re-uses the selector tool's code then snapping should probably already work, so I guess some code has been duplicated.

Reproduced on Ubuntu 10.04, Inkscape r9535.

As expected, this also affects dragging the rotation center of a selection of nodes -> no snapping (r9636).

for some first test

Fully implemented as of rev. #10633

@Diederik - many thanks! (much appreciated :) )

Allow me to add a question about a small related issue: any chance that bug #590260 could be revisited (show all four skew handles for horizontally or vertically aligned nodes (i.e. straight line segments) like in the select tool)?

@~suv: Thank you too!

I've asked Krzysztof to reconsider his opinion, which he expressed in
comment #5 of that bug report. It's his work, so it should be his call IMHO.
