Xcos: blue connection lines/wires do not snap to grid

[Crypto]

Hi,

Scilab 5.2.1-3 debian packages running here, taken from the standard debian 
repositories.

There appears to be a problem with how Xcos draws parts and aligns the 
connection lines to the grid.

Steps to reproduce:

1.) Run Scilab and then open an Xcos demonstration file, e.g. the RLC_circuit 
(the following description relates to this file).

The parts and connection lines of the circuit are matching/aligning to the 
grid, I would think.

But there are some blue connection lines which do not. Instead, they run in 
slight "ramps", e.g. the GND connection wire to the bottom left, and the two 
blue wires running to the MScope to the right.

Also, the blue connection wires sometimes poke into the white connection spots 
of the parts, this happens e.g. with the current sensor and the voltmeter, but 
also with the vertical inductor and capacitor.

This seems to be related to how Xcos scales/zooms the GUI representation of a 
component and aligns it to the grid.

When I select a component I can resize it with the mouse, but there is no way 
for me to scale it using the grid, i.e. no matter how I scale the component it 
never "snaps" to the grid so I never know if I have scaled it correctly. There 
also is now way of reverting the component to 100% of its original size, and 
there is no option to scale/zoom a component by equally increasing size in 
both x and y direction (like with a square - sometimes programs offer to zoom 
in such a way by holding down the STRG button).

These are not really terrible bugs, but something that risks the prettyness of 
how Xcos displays circuits ;-)

Kind regards,
Crypto.
